Kevin Spacey, who was already being investigated over a sexual assault in 2008, is now the subject of a police inquiry dating back to 2005

Kevin Spacey is being investigated by Scotland Yard over a second allegation of sexual assault.

PEOPLE has confirmed that the 58-year-old Oscar winner has been accused of sexually assaulting a man in Lambeth, London, in 2005. Spacey was already being investigated by Scotland Yard over a sexual assault in 2008.

“On Wednesday, November 1, City of London Police referred an allegation of sexual assault to the Metropolitan Police Service,” a Scotland Yard spokesman told PEOPLE in a prepared statement that did not directly name the actor.

“It is alleged a man assaulted another man (Victim 1) in 2008 in Lambeth. On Friday, November 17 a further allegation was made about the same man.

“The allegations are of sexual assaults against a man (Victim 2) in 2005 in Lambeth. Officers from the Child Abuse and Sexual Offences Command are investigating.”

The new allegation comes on the heels of an internal investigation by the Old Vic theater — of which Spacey was artistic director from 2004-15 — that revealed 20 separate individuals had accused Spacey of inappropriate behavior toward them. However, it’s not known if this new investigation relates to one of these complaints or is entirely separate.

Spacey is currently checked into a specialist treatment facility following the numerous allegations of sexual assault that have been made against him, PEOPLE confirmed last week.

Spacey’s team has not responded to any of the accusations ever since he expressed regret for allegedly making inappropriate sexual advances toward actor Anthony Rapp, then 14 years old, in 1986.

Spacey issued a statement saying he doesn’t remember the alleged incident, apologizing for “for what would have been deeply inappropriate drunken behavior” and announcing, “I choose now to live as a gay man.”
