British police are investigating the death of a young film maker who was sleeping rough while making a documentary about the homeless.
The body of Lee Halpin, 26, was found in a derelict building in the northeastern English city of Newcastle last weekm, just three days after he began the project.
Police said they had arrested two men, aged 26 and 30, in connection with his death on suspicion of supplying a controlled drug. Both were later bailed.

A post mortem into the cause of his death is due to be carried out on later this week.
Speaking on a YouTube video the night before he began sleeping rough on Sunday, Halpin said he wanted to "interact with as many homeless people as possible and immerse myself in that lifestyle as deeply as I can."
A friend said Halpin could have frozen to death as Britain has spent the last few weeks in the grip of freezing weather.
"No one knows how he passed away, but we think it could have been hypothermia," his friend Daniel Lake told local newspaper The Chronicle.
Broadcaster Channel 4, for whom Halpin said he was making the video as part of an application for an investigative journalist scheme, said it was "saddened to learn of the tragic death of this aspiring young journalist."
A small group of the filmmaker's friends, some of whom were helping him on the project, have vowed to finish Halpin's documentary as a tribute to him.
The group has set up Facebook, Twitter and blog accounts to spread the word of Halpin's death and homelessness in the UK.
