Former BBC Radio 1 DJ Tim Westwood has been interviewed under caution for a fourth time by the Metropolitan Police, BBC News understands.

Officers are investigating a number of reports relating to allegations of non-recent sexual offences allegedly committed by a man.

In a statement, police said the offences are alleged to have happened between 1982 and 2016.

Detectives said they interviewed a 66-year-old man under caution on Thursday.

They also interviewed a man under caution in March, April and July this year. There has been no arrest.

This comes after BBC News and Guardian investigations uncovered multiple allegations from 18 women of serious sexual misconduct and abuse by Mr Westwood.

He denied those allegations.

In April 2022, several women accused the former Radio 1 and 1Xtra DJ of predatory and unwanted sexual behaviour and touching, in incidents between 1992 and 2017.

They also accused him of abusing his position in the music industry. Some of the women said they encountered Mr Westwood when they were under 18. One said she was only 14 when Mr Westwood first had sex with her.

That same month, the DJ stepped down from his Capital Xtra radio show.

Mr Westwood has continued to play in gigs up and down the country, despite some campaigners calling for nightclubs not to host him since the allegations emerged. Last week, in a video that appeared on social media, the DJ was asked whether the allegations were true.

He replied: "It's all false allegations. It's all false allegations. I've never done that, period, they're all false allegations. I will prove that as soon as I get my opportunity and trust me, I am ready."

An external report, by KC Gemma White, commissioned by the BBC and looking at what the corporation did and didn't know about Mr Westwood's conduct during his near 20-year employment with the broadcaster, is due to be published this year.
