Conference 2014 | Conference ovation for presentation on officer deaths
The man who was in charge the day two GMP police officers were shot dead received a standing ovation at this year's Police Federation of England and Wales conference.
Ch Supt Nick Adderley, divisional commander for Tameside, told officers about the day PC Fiona Bone and PC Nicola Hughes were shot dead in September 2012.
He said it was the "darkest day in the force's history" and that the events would remain with him until the day he died.
Dale Cregan pleaded guilty to the murders of the two officers after he lured them to an address in Hattersley on 18 September 2012 with a fictitious report of a burglary before shooting them dead.
Ch Supt Adderley told the conference how he experienced an "out of body" experience when he heard that the two officers had been shot and that he has gone on to put together post incident guidance for forces where police officers experience the trauma of losing officers.
He said: "Afterwards, all staff were given the option to stay away from work and return when they were ready. There were some members of that team that were back at work the next day. To me, that is bravery personified. But we needed to identify those most badly affected. Several members of staff are still off work. If you try and draw people back to work too soon, you will pay for it in the long run."
He paid tribute to Greater Manchester Police Federation for its work in supporting the officers, describing them as the "real leaders" following the shooting.
