A man made off with £25 after pinning a teenager against a wall and threatening to stab him in the early hours of this morning in Northampton.
Detectives say a second man stood and watched the town centre robbery at about 2.15am today (Thursday February 20) in Bridge Street.
The 18-year-old victim – who was on a night out in the town – was approached by another man close to the Lloyds cash point.
A spokesman for Northamptonshire Police said: "The man pinned the teenager against a wall and threatened to stab him if he didn’t hand over his cash.
"Although no knife was seen, he handed over £25 in cash.
"The offender is described as a black man, in his early 20s, about 6ft, of a slim build with dreadlocks. He was wearing a red shirt with a dark top underneath and dark jeans.
"A second man, who was with the offender, stood and watched the robbery. He is described as being of dual-heritage, also in his early 20s, about 6ft, of a heavy build with short shaven hair. He was wearing a black puffa-style jacket.
