Met officers take a fully-automatic pistol off the streets of Croydon

A Met investigation has led to the arrest and conviction of a Croydon man for the possession of an illegal firearm and drug distribution. 

Mark Kerwick, 33 (20.03.91), of Shrublands Estate, Croydon was sentenced to five years’ imprisonment at Croydon Crown Court on Tuesday, 11 June.  

Kerwick was found guilty of possession of a firearm, and distributing Class B drugs at an earlier hearing at the same court.

Detective Constable Samuel Cafferty, from the Specialist Crime Command, who led the investigation, said: “Drugs have a devastating impacts on communities and it goes without saying that guns such as these can cause serious violence an irreparable damage. 

“Our team collaborates with local officers to dismantle firearm-related crimes in Croydon. The swift action taken by the officers demonstrates our dedication to maintaining public safety and combating criminal activity within London. 

"To further enhance our efforts, we have also increased patrols in high-risk areas serving as a visible deterrent to potential offenders and reassuring the public of their safety. If you have any questions, please speak to local officers who will be happy to hear from you.” 

In October 2020 a dry cleaners in Thornton Heath, Croydon was raided and during the search of an out-building in the back yard of the premises, a converted Glock pistol capable of fully automatic fire was found in a black zip up pouch.  

Kerwick claimed he had picked up the gun in 2016 or 2017 but had only held it for about five seconds. However forensic investigation by Met officers found Kerwick’s DNA on the trigger and working parts of the pistol, as well as internal components.   

As part of the investigation, specialist officers also analysed the contents of Kerwick’s phone and discovered he had been supplying cannabis to friends and family.  

As part of the Commissioner’s vision for the New Met for London, we are putting more support into local policing from both community teams and the wider Met, focusing on the issues that matter to Londoners.
