Scotland Yard has been investigating allegations of sexual assault on three men in London, spanning from 2005 to 2008.
The Oscar-winning actor was accused of sexual assault by a number of men during the #MeToo movement, leading to authorities in both the US and the United Kingdom - where he often worked - opening criminal investigations against him.
Spacey also is facing criminal investigation in the United States after an 18-year-old reported to authorities in November that Spacey grabbed his genitals in a Nantucket, Mass., bar in 2016.
Spacey, 58, became embroiled in controversy a year ago when actor Anthony Rapp accused him of trying to seduce him in 1986 when Rapp was 14.More news: Little light snow, rain around Monday night, Tuesday morning
Spacey, now 58, said he did not remember the encounter but apologised for any "inappropriate drunken behaviour".
As the number of alleged incidents escalated, Netflix cut Spacey from his lead role in the award-winning series "House of Cards". He also was replaced by Christopher Plummer in the Oscar-nominated offense thriller "All the Money in the World".
The nature and origin of the sexual assault accusation was not disclosed.More news: Rio Tinto plc (LON:RIO) Ratings Summary as of April 11, 2018
