Attacker's rooftop stand-off footage released by Humberside Police

Video footage recorded by Humberside Police's helicopter reveals the moment a "violent" attacker hurled tiles from a rooftop in a stand-off with officers.

Clint Clay, 24, , of Frodingham Road, Scunthorpe, assaulted Jason Potts with a machete and a hammer before taking to the roof of a house on Alexandra Road in Scunthorpe on 6 July last year.

He denied assault and three other charges but admitted affray, and was sentenced at Grimsby Crown Court on Monday.
