A teenager carrying a machete is seen threatening a female shop worker while his accomplice, armed with a sword, steals cash, cigarettes and alcohol, in CCTV footage released by police.

The pair, said to be aged between 16 and 18, had their faces covered and wore goggles when they entered the off-licence in Church Road, Mitcham, south London.

The first suspect, wearing a backpack containing a sword, walks behind the counter while the second raises the machete and then appears to act as a lookout.

He is then seen joining his accomplice behind the counter and lifting items from the shelves.

The teen carrying the backpack was wearing a black jacket, black shoes and black goggles.

The other teen, wielding the machete, is described as being of a thin build and around 5ft 6ins tall. He wore a black hat, black jacket, black shoes and red goggles.

Both wore gloves during the incident shortly after 11pm on November 13.

Police have released the footage in a bid to identify the teenagers.
