The Delhi police on Saturday claimed to have solved the murder of two homosexuals -- United Nations Development Programme employee Pushkin Chandra and his friend Kuldeep -- with the arrest of three persons, including one of the two alleged killers.

The main accused, Rajesh, 24, was arrested from Chattarpur in Madhya Pradesh in the morning, Commissioner K K Paul said in New Delhi.

The police have identified the second killer as Moti alias Mohit of Nepalese origin, who is still absconding.

Paul said it emerged from preliminary investigation that Chandra knew the killers and he had picked them up on the day of the murder from Connaught Place.

They, along with Kuldeep, had then gone to attend a party thrown by Danish national Uffe Gartner.

"All four returned from the party to Pushkin's house in Anand Lok Apartments in south Delhi, where the murder took place," Paul said.

On the motive of the crime, the officer said, "From preliminary interrogation, it seems that Pushkin tried to click photos of Rajesh and Moti with his polaroid camera, which enraged the two and they stabbed him and Kuldeep."

Pushkin and Kuldeep were found murdered in the former's apartment on August 14.

A number of the UNDP employee's belongings, including his car, credit cards, polaroid camera, a laptop were found missing from the scene of crime.
