Video: Sir Hugh Orde defends the operation that led to shooting in manchester Sir Hugh defended the police's decision to release Cregan on bail in the months before yesterday's incident. Mr Cregan was arrested at Manchester airport on June 12 as he returned from a holiday in Thailand and questioned over the murder. Sir Hugh said: "It's a routine police tactic is to arrest someone, interview them, to start to build a case. Sometimes those people are rearrested, sometimes they are found to be entirely innocent and therefore not required to return. There very strict rules about how long you can keep someone in custody. The unarmed officers, Fiona Bone, 32, and Nicola Hughes, 23, assumed the call was routine. There was no intelligence to suggest the home was anything other than the scene of a run of the mill break-in.
