A man having his hair cut leapt out of the barber's chair and ran to help a police officer who was being wrestled to the ground in a headlock.
Kyle Whiting was having a trim at Heron Barbers in Warrington, Cheshire, when he looked through the window and saw the officer being confronted.
The 32-year-old dashed out of the shop - with the barber's cape still draped around his shoulders - before dragging the man off the officer and giving him time to handcuff the suspect.
Mobile phone footage of the incident was shared on social media, with people praising the "barbershop Batman", "haircut hero", and "caped crusader".
