The dynamic duo in action

The caped crusader’s secret identity is out – and it’s not Bruce Wayne.

39-year-old Stan Worby has admitted he was the man who last week, dressed as Batman, walked into a British police station in the middle of the night and told officers "I've caught this one for you" as he handed them a crime suspect.

Wearing the full costume of the shadowy comic book hero, including a cape, he then "promptly vanished into the night to fight crime and the fear of crime in Bradford", West Yorkshire Police said.

The police posted CCTV photographs of the "caped crusader" arriving at the police station with his captive on their Facebook page.

The post sparked a slew of theories on social networking sites about the identity of the crime fighter, leading Worby to come forward and tell of his crime-fighting exploits.

In fact it turned out the 27-year-old crime suspect, Danny Frayne, who will appear in court on Friday charged with handling stolen goods and fraud-related offences, was a friend of Worby’s, who’d asked for a lift to hand himself in.

But Worby, whose day job is as a Chinese takeaway driver, was busy seeing a soccer match at Wembley – dressed as Batman, in the 1960s Adam West style. (If a little tubbier.)

"I told him as soon as I was home I would run him to Bradford central police station. We got back about 1am, and I picked Danny up in a minibus at 1.30am.,” said Worby.

"I got some strange looks when I got to the cop station though. One policeman looked at me and just laughed.

"I said to the policeman, 'I deserve a medal, I'm a caped crusader'."

Worby said he’d tried to convince his old friend Frayne during the week to hand himself in, after police had been asking after his whereabouts.

If only that technique had worked with the Joker.
