Three masked and hooded men threatened staff and customers when they tried to rob a shop in Colliers Wood.

Police have released dramatic pictures of the moment the men burst into the 02 store in the Tandem Centre at 12.45pm on Sunday (October 1).

Police say the men were armed and hiding their faces as they threatened staff and customers, but failed to steal anything before making their escape.

Witnesses describe the suspects as black between the ages of 18 and 20.

The Met Police at Merton Merton police have released the pictures in an appeal to identify the suspects.
