Item from Metropolitan Police:

A group of 37 gun traders and drug suppliers have been sentenced to a total in excess of 400 years imprisonment following Operation Peyzac, a successful Metropolitan Police Service undercover sting operation designed to target serious and organised crime in and around Enfield borough in response to a spate of murders in Enfield in 2008 and intelligence suggesting that gangs were operating in the area.

In order to gain information about the gangs, detectives launched a covert fully stocked and functioning music shop called the Boombox in a busy Edmonton shopping area. Officers filmed the trading of firearms, ammunition and drugs during the 12 month period the shop operated. One man was filmed selling officers four loaded guns, having travelled with them on a bus, another was filmed handing over cocaine with a street value of £4,000.
