Deputy Prime Minister Nick Clegg has joined top officers in warning against any knee-jerk calls to arm all police, following the death of two constables in Greater Manchester.

Meanwhile, colleagues from the force have held a minute's silence for PCs Fiona Bone and Nicola Hughes - who were shot dead yesterday ... and a special service has been held at a local church.

Detectives are continuing to question 29 year old Dale Cregan about the killings - and two earlier murders.
