A Tory backbencher chased down and detained an alleged shoplifter in his Essex constituency.
Douglas Carswell said he saw the man running down Pier Avenue in Clacton with items falling out of his pockets and store detectives in pursuit.
After outpacing the suspect and pinning him against a wall, he told him: "You probably don't want to hear this, but I'm your local MP."
Mr Carswell, who runs daily to keep fit, said he took action after seeing the man, aged in his late 20s or early 30s, apparently trying to make his escape.
The MP joked that he was tempted to take a 'selfie' photograph after capturing the individual, but decided just to put the news on Twitter instead.
He said when the police arrived they thanked him for his efforts, and took the suspect away.
Clacton MP Douglas Carswell has been tweeting about how he foiled a would-be shoplifter.
The Conservative MP for Clacton, Douglas Carswell, voted in favour of the government motion on Syria which was defeated by the House of Commons by 285 votes to 272.
