Two men have been arrested as part of the police inquiry sparked by claims of abuse against Jimmy Savile.
The Metropolitan Police said the men, aged 64 and 74, were held at separate addresses in south London.
They were arrested on suspicion of historical sexual offences and taken into police custody.
The men are the 15th and 16th people to be arrested as part of Operation Yewtree, the police investigation launched after Savile's death in 2011.
The nationwide inquiry was launched after claims of sexual abuse were made against the former BBC radio DJ and television presenter, who died aged 84.
It has three strands - one is looking specifically at the actions of Savile, while the second strand concerns allegations against "Savile and others".
The latest arrests fall under the "others" strand.
The third strand relates to allegations against other people unconnected to the Savile investigation.
