Former BBC Radio 1 DJ Tim Westwood has been questioned twice under police caution over five alleged sex offences.
The alleged offences go back 40 years, between 1982 and 2016, according to the Met Police.
Scotland Yard said detectives interviewed a 65-year-old man under caution on 15 March and 4 April.
No arrests have been made.
Detectives first received claims of sex assaults in April last year, after the BBC aired a documentary revealing allegations against the presenter from seven women.
Westwood strongly denied any wrongdoing.
Soon after, police began assessing more reports, including alleged assaults in London, Essex and Hertfordshire.
The BBC later reported allegations from another 10 women, one claiming she had begun having sex with Westwood after meeting him at a club when she was 14.
A Metropolitan Police spokesperson said: “Police are investigating five reports relating to allegations of non-recent sexual offences allegedly committed by a man.
“The offences are alleged to have occurred in London between 1982 and 2016.
“A 65-year-old man was interviewed under caution on 15 March 2023 and 4 April 2023.”
The pioneering hip-hop DJ worked for BBC Radio 1 from 1994 to 2013 and has had a huge following as a club performer.
He stood down from his radio show on Capital Xtra in April last year when the BBC allegations emerged, with women alleging predatory and unwanted sexual behaviour and abuse of his position in the music industry.
