A pervert who exposed himself in a pub and performed a sex act in front of customers has been jailed.

David Nightingale, 75, who has previous convictions for exposure, entered the pub in Parker Lane, Burnley, around 5.30pm on June 30.

Around an hour later the female victim noticed he had unzipped his trousers and was performing a lewd act.

When the shocked victim told her partner what he was doing, Nightingale covered himself up and left.

He was identified via CCTV and arrested yesterday morning (July 13).

Following consultation with the Crown Prosecution Service, Nightingale, of Acre Avenue, Bacup, was charged with exposure.

He pleaded guilty at Blackburn Magistrates' Court this morning and was sentenced to 18 weeks in jail.

He was ordered to sign the Sex Offenders Register for seven years.

DC Leigh Palfreeman, of Burnley CID, said: “Nightingale’s behaviour was disgusting and understandably left the victim shocked.

“This is not the first time he has engaged in such worrying behaviour.

"I am pleased he has now been given a custodial sentence and that he will have to inform police about his movements for the next seven years.”
