The detective who caught the prolific cyberstalker Alex Belfield fears he has restarted his online campaign of vitriol after being released from prison.

Detective Constable Janet Percival began building the case against the former DJ for BBC Radio Leeds in 2019.

It was thanks in large part to her efforts that in August 2022, Belfield, 45, was found guilty of stalking four people and jailed for five and a half years the following month.

His victims included the Radio 2 presenter Jeremy Vine, who dubbed Belfield 'the Jimmy Savile of trolling after being subjected to 'an avalanche of hatred' of repeated abusive messages, videos and emails.

But although he was only freed from prison in June, after serving half his sentence in HMP Fosse Way in Leicestershire, Percival argues that Belfield has once again returned to his online trolling pastime.
