Police are continuing to question a man arrested on suspicion of terrorism offences after a woman was stabbed in Cheltenham.
While a spokesperson for GCHQ told ITV News its policy is never to confirm or deny the identity of its current or former staff, it has been reported the victim was an American spy who had been seconded to GCHQ.
Gloucestershire Police were called to Tommy Taylors Lane on Thursday (9 March) to reports a woman had been injured outside a leisure centre.
