ROCK star Pete Doherty was a guest at an east London party at which an actor fell to his death on Sunday night.

Actor Mark Blanco fell from the second floor balcony of a block of flats on Romford Street, in Whitechapel, early Sunday morning.

Mr Blanco was rushed to Royal London Hospital shortly after 1am, but died from his injuries on Monday.

Police said it did not appear that there was anyone else involved in his death.

"At this early stage it does not appear there was any third party involvement in the incident. However, police retain an open mind and enquires by Limehouse CID continue," a police spokesman said.

The 30-year-old, from Tower Hamlets, in east London, was due to star in a new London play, The Accidental Death of an Anarchist, next week.

The play is about a man who fell to his death from a police station window.

According to reports, Babyshambles singer Doherty had been trying to clam an excitable Mr Blanco down shortly before he died.

Paul Roundhill, who owns the flat where the tragedy struck, denied a report in The Sun that Doherty had fought with Mr Blanco before he died.

"Pete wasn't involved at all. He was so upset at what happened. There was no fighting, Peter wasn't involved anyway apart from to help and to calm Mark down before the accident," he told National News.

"They didn't have an argument. Mark was talking to Peter very excitedly about his play.

"He was excited about that. There wasn't a party at the flat, there was two girls and me and then a few more people including Pete came."

There is no suggestion that Doherty played any part in his death.

A post-mortem at the Royal London Hospital today found the cause of death was severe head injuries consistent with a fall.

An inquest will open and adjourn at Poplar Coroner's Court tomorrow. There have been no arrests.

The night after the party Doherty escaped jail and was fined £770 for drug possession at Thames Magistrates Court.
