The other was in a stable condition in a general ward, hospital spokeswoman Philippa Johnson said on Tuesday.

Johnson could not release the names of the survivors.

Ten men were shot in the head at close range in the Graham Road, Sea Point brothel about 4am on Monday.

The victims were all found with their hands tied behind their backs, most with their throats also slit.

The massacre has been met with outrage from politicians, sex workers and gay rights activists.

Safety and security MEC Leonard Ramatlakane, who visited the scene, appealed to the public to come forward with information on the gruesome attack.

Police spokesman Captain Etienne Terblanche said the investigation was at an early stage and he did not wish to speculate about possible motives.

This was in reply to a question posed by the media as to whether the killing had anything to do with Nigerian drug dealers or a protection and racketeering scheme.

Earlier, some neighbours had said they were fed up with the number of Nigerians in the area. They all declined to be identified.

Terblanche said an investigation task team along with members of the serious violent crimes, organised crime and crime intelligence units had been formed to handle the investigation.

Eight men died after they were shot dead execution style in a house in Graham Road shortly before 4am. They were found with their hands bound behind their backs. Most of them had their throats slit.

Two other men, who suffered similar injuries, were being treated at Groote Schuur Hospital.

Hospital representative Philippa Johnson said one man was critical while the other was stable. One was in his 50s while the other was in his 20s.

Police representative Captain Etienne Terblanche said one of the suspects had a tattoo of a curled-up snake on his upper left arm, and the words "fast gun" tattooed on his right wrist. His hair was reddish, probably bleached, and he had a goatee beard.

The second suspect was a thin man with a fair complexion who had a habit of sniffing.

The third suspect was tall and well-built with a shaven head and was possibly a body builder while the fourth was also described as well-built.

"All these suspects were seen driving a white three series BMW," Terblanche said.

The massacre has been met with outrage from politicians, sex workers and gay rights activists.

Safety and security MEC Leonard Ramatlakane, who visited the scene, appealed to the public to come forward with information on the gruesome attack.

"It is shocking to see human beings massacred in that way. It is clearly a planned execution, which suggests that it is a matter of organised crime," the MEC told reporters.

Ramatlakane confirmed that a high-level integrated police task team had been established to investigate the crime which would be looked at from all angles.

"No stone will be left unturned to ensure that the perpetrators of this despicable crime are brought to book," Ramatlakane said.

The bodies of five men were found in the main bedroom of the Graham Road house, a well-known all-male massage parlour operating under the name "Sizzlers". A sixth body was found in an adjacent room.

When police arrived on the scene they encountered three men, horrendously wounded, crawling about in agony on the wooden floor of a room in the house.

A fourth man had somehow managed to escape, although he too had been shot in the head. He made his way to a nearby filling station where he told the attendant what had happened before he collapsed.

Three of the injured were rushed to the Groote Schuur Hospital where two had died.

The men were all tied up with packaging tape and made to lie face down on the floor in a row in the communal bedroom. They had all been shot in the back of the head and most had their throats slit.

Terblanche described the scene as "horrendous".

According to neighbourhood residents Graham Road was a quiet area, and there had been no problems at No 7 during the daytime.

But Terblanche said police were at times summoned out at night after receiving complaints of rowdiness and drunkenness.

Terblanche said it may take some time to identify the victims as many of the men who usually frequented such establishments used aliases. He said the police investigation was at an early stage and he did not wish to speculate about possible motives.

This was in reply to a question posed by the media as to whether the killing had anything to do with Nigerian drug dealers or a protection racketeering scheme.

Earlier some neighbours had said they were fed up with the number of Nigerians in the area. They all declined to be identified.

Terblanche said an investigation task team along with members of the serious violent crimes, organised crime and crime intelligence units had been formed to handle the investigation.

A team of detectives had interviewed several people in the vicinity of the crime scene to find possible witnesses.

Forensic detectives spent virtually the entire morning combing the crime scene for clues.

Terblanche said further information would be released when it became available.

Scenes of utter chaos greeted journalists when they were finally allowed into the main bedroom of the red-tiled house one at a time and more than seven hours after the men were murdered.

The outside of the picket-fenced property, with its garden of trees and flowers partly hiding the house from the road, appeared neat and tidy. It gave no clue as to what had transpired inside.

The main bedroom was dark and dinghy. Heavy curtains covered the windows and there was blood everywhere.

The room contained six bunks piled on top of each other apparently for guests wanting to spend the night.

The room appeared to have been ransacked with items of clothing and teddy bears littering the floor.

Inside the house there were also television sets and video cassette records but police, asked, did not divulge what was on the tapes.

There were also cubicles inside the house equipped with massage tables and pornographic photographs of men glued to the walls.

Around 9.30am a woman, apparently a domestic worker arrived at No 7 and, immediately she saw the mayhem, started crying uncontrollably.

"Where's Eric, where's Eric," she wailed as she was comforted by a policewoman. She was escorted from the scene. It could not be confirmed, but Eric is believed to have owned or managed the massage parlour.

The United Democratic Party (UDM) condemned the killings and called on the authorities to prioritise "this senseless crime".

The Sex Worker Education and Advocacy Taskforce (Sweat) said it was dismayed by the killings.

"As an organisation that advocates and lobby for the human rights of sex workers, we are distressed to hear that sex workers were part (sic) of the 10 men that were attacked," Sweat co-ordinator Althea Macquene said in a statement.

"Currently sex work in South Africa is dangerous work. The present law that criminalises sex work forces the sex industry to operate underground with no protection or regulation.

"This situation opens up the industry to criminal activity and sex workers are particularly vulnerable to criminal related activities and violence," Macquene said.

The Lesbian and Gay Equality Project in its reaction to the massacre said it was shocked.

The organisation's director Evert Knoesen said indications were that the murders could be a hate crime.

"People who work in the sex service industry are particularly vulnerable (to violence) as they operate outside the parameters of formal society."

A local flat owner who declined to be identified said he had been awakened by shots and had seen a man with a gaping wound to his neck, staggering up Oliver Street to a service station in Main Road.

He said 15 police vehicles and four ambulances had converged on the scene shortly after 4pm. All roads leading to Graham road were immediately sealed off.

Another elderly couple, out from the United Kingdom to escape the British winter said they had heard the shots from their nearby flat.

"We came here from England to escape the weather and this is what happens," said the husband, who did not wish to be named.

"At the age of 77, you've seen quite enough so nothing surprises you anymore," they said.
