A 15-year-old boy has been arrested as police seized this huge “zombie knife” from him in Worcester Park.

Officers from Syndicate 19 VCTF executed a warrant and detained the teenager on suspicion of importing the weapon.

A second boy, who is 14, was also at the address and arrested on suspicion of importing an “adapted” knuckle duster.

Sutton police published an image of the “zombie knife” on Facebook, drawing a wide range of responses from social media users.

Some praised the work of the officers while others questioned how the teenagers got hold of the weapons in the first place.

The post added: “Great work by the team, seizing these weapons before they can be used in violence.”
