A 15-year-old boy has been arrested in connection with the murders of two police officers in Greater Manchester.
Police said the boy, who was detained in Hattersley on suspicion of assisting an offender, has been bailed until 27 September.
Earlier, Dale Cregan appeared at Manchester magistrates’ court, charged with the murders of PC Nicola Hughes and PC Fiona Bone.
Mr Cregan is also charged with the murders of Mark Short and David Short.
PCs Hughes and Bone died after they were called to reports of a burglary in Hattersley on Tuesday.
Mr Short and his son were murdered in separate incidents earlier this year in Clayton and Droylsden.
