Police in Burnley issued a witness appeal after a semi-nude chubby super hero exposed himself to two joggers.
The women were on the Hapton/Padiham Greenway between Molly Wood Lane and Knotts Lane when he called to them from the undergrowth near the Leeds and Liverpool Canal.
They turned round to see the clean-shaven flasher in his blue super-hero half mask and stripped blue and white T-shirt, but without trousers or underpants. He was white, and 5ft 8in tall.
Anyone with information is asked to ring the police on 101.
