Police said the bungalow in DHA Phase VII, Khayaban-i-Rahat, had been rented by one Faisal and the party had been organised by a person named Saif.
The organisers had sought security assistance from a political party.
Talei Bugti, police said, entered the bungalow after agreeing to leave his armed escort outside. Clifton SP Tariq Dharejo said: “The shootout began after a heated argument between Mr Bugti and the organisers first inside the bungalow and later outside.”
Mark Joseph, Kamran Shafi, Dr Iqbal and Kamran Gul died on the spot while Mr Bugti who suffered gunshot wounds in the chest was taken to a private hospital where he died.
Another injured man, Ziauddin, died in a hospital on Sunday afternoon.
According to a law-enforcement official, the party was well organised with paid entry. The organisers had made arrangement for valet parking.
The official, who visited the house after the bodies and injured had been removed said there were spots of blood all over the place because the injured might have rushed inside. There were traces of blood in the swimming pool as well.
The arrangement for the party, he said, was quite elaborate with two bars and a DJ system.
He said the owner of the bungalow, Nasir Khan, was there when the firing took place.
He told police that he had rented the premises to Faisal and Saif for the night for Rs20,000.
The SP was not sure if any weapon had been seized from the place or from some people detained by police. “We are verifying” details, he said.
Another police official claimed that the sound system and some cars and motorcycles had been impounded from the premises.
Spent bullet casings of 9mm pistols and AK-47 rifles had been found, police said.
Although police claimed to have detained nine suspects from the place, sources said no-one involved in the firing as among them. The source said a number of injured people and four bodies had been taken to the Jinnah Postgraduate Medical Centre at about 3am.
According to hospital sources, almost all of them had been hit by bullets fired from a close range.
The funeral prayers of Talei Bugti were held in Sultan Masjid and he was buried in the Phase IV graveyard.
Although the organisers claimed that they had the Defence Housing Authority’s permission to hold the party, law-enforcement officials said the permission was for a private party, not for a commercial event.
