A man dressed as the caped crusader Batman has handed over a wanted man at a Bradford police station before disappearing into the night.
Police said the costumed man did not reveal his identity.
Police said the costumed crime-fighter marched the 27-year-old man into Trafalgar House Police Station in the early hours of 25 February.
The man was charged with handling stolen goods and fraud offences. Police said: "The person who brought the man in was dressed in a full Batman outfit. His identity remains unknown."
The suspect will appear before Bradford magistrates on Friday, police said.
