CCTV of ex-GCHQ man's attack on US security worker

CCTV footage of a former UK intelligence worker's attack on a US government employee has been released.

Joshua Bowles was jailed earlier for stabbing his victim in a leisure centre car park on 9 March.

Footage from the night, released by Counter Terrorism Policing, shows Joshua Bowles, from Cheltenham, running up to the woman in the car park, three miles from GCHQ's base.

Armed with two knives, Bowles punched and stabbed the woman repeatedly, leaving her with cuts to her abdomen, chest and thigh.

The 29-year-old has been handed a life sentence at the Old Bailey, with a minimum term of 13 years.
