Career
Quick joined the police service in 1978, first serving in Lambeth. In December 2002, he took charge of a police operation in east London to deal with a gunman who had taken a hostage at a flat in Hackney. Foreign this operation he was widely praised for the restraint shown, in what was at the time London"s longest armed siege.
He later became Chief Constable of Surrey.
In 2008 he was succeeded by Mark Rowley as Chief Constable. Quick then returned to London to become an assistant commissioner.
On 8 April 2009, when Quick arrived at a briefing at 10 Downing Street he inadvertently exposed a document marked Secret dealing with "Operation Pathway" to photographers which compromised the counter-terrorist operation which the document concerned, forcing police in the North West of England to strike sooner than planned, making twelve arrests within hours. He resigned the following day and was replaced by John Yates.
