Manchester shootings: surprise of parents of arrested teenager The boy was detained at his school in Thameside, Manchester, on Friday by three plain-clothed officers who handcuffed him and led him away. He was held for six hours before being released on bail pending further inquiries. Cregan, 29, was remanded in custody on Friday charged with the murders of Pcs Fiona Bone, 32, and Nicola Hughes, 23, of Greater Manchester Police, along with two further murders and four attempted murders. The father of the arrested boy, who cannot be named, said: "My lad's never met Dale Cregan in his life. It's unbelievable. I understand that the police have a difficult job to do but it doesn't make any sense to me and I'm just trying to get to the bottom of how this could have happened. Garry Shewan, Assistant Chief Constable at Greater Manchester Police, said: "This remains a complex and sensitive investigation and we continue to ask the public to search their conscience and urge anyone who has any information to contact us." The chief constable of Wiltshire police also said that he plans to issue more officers with Taser stun guns to stop them feeling "vulnerable." Patrick Geenty said: "Training more officers to use Tasers would do more to protect them ... I'm looking to see whether we can increase that.
