One of Britain's top policemen's warning against a rush to arm all officers following the deaths of two constables in Manchester.

Detectives are continuing to question 29 year old Dale Cregan about the killing of Fiona Bone and Nicola Hughes yesterday - and two other murders.

But the president of the Association of Chief Police Officers, Sir Hugh Orde, thinks guns could make his members more of a target.

Meanwhile, officers from the Greater Manchester force have held a minute's silence for their colleagues - and a special service has been taking place at a church close to the scene of the killings.
