A BBC investigation into the death of Mark Blanco, the man who died at a party attended by Pete Doherty, suggests he died after being 'dropped' from a first floor balcony.

Doherty and his minder Jonathan Jeannevol had been implicated in the man's death because Blanco had apparently 'annoyed' the former Libertines frontman at the party. After Blanco's death Doherty left the party, passing the man on the floor below.

Although police found that his death was not suspicious, a BBC investigation now suggests that CCTV footage appears to show Blanco being dropped from the balcony.

"There's no defensive movement whatsoever," says Grant Fredericks, a US video forensics expert. "It's literally a drop from outside the rail. The only explanation I can think of is that somebody might have dropped him off the balcony.

"He doesn't climb over the railing himself. He doesn't jump. He just suddenly appears outside the railing and falls."

Blanco's mother, Sheila Blanco has now lodged an appeal over the death of her son after the incident in 2006.

An IPCC spokeswoman toldd WENN: "There was a complaint made to the Met Police. They sometimes come to us or they investigate themselves. I think in this case they investigated themselves and Mrs. Blanco is not happy with the outcome so she has appealed to us.

"So that is the situation being dealt with. We have just received it last month. We are looking at the appeal. We look to see whether the investigation does what it said it would do."

A Met Police spokesperson said: “We received a complaint in response to various aspects of the original investigation. An investigation by the director of professional standards was launched. The investigation is now complete. An appeal has been lodged by the complainant with the IPCC."
