The Libertines singer Pete Doherty has been interviewed by police after a death at a party in December 2006.
Mark Blanco, 30, died at a party that was also attended by Doherty after falling from a balcony in Whitechapel, east London.
Initial investigations by Scotland Yard said that the man had jumped deliberately, but coroner ordered a second investigation by an independent person in 2007.
According to Sean Curran, Doherty’s solicitor, the singer voluntarily attended a police station ”to help them with their inquiries”.
A Metropolitan Police spokesman said: “We have made no arrests.
“Inquiries continue and we are not prepared to discuss who we may or may not have spoken to.”
Mr Blanco’s family are paying for their own specialist reports on how he suffered the fatal head injury that caused his death after the coroner’s ruling.
This private investigation comes after expert Professor Richard Wassersug said had the Cambridge graduate deliberately jumped, he would have suffered different injuries.
