A robber threatened two members of Greggs staff with a knife and made off with cash in Southsea.
Police said a man entered the store in Palmerston Road between 5.25pm and 5.40pm yesterday.
He approached the counter and started shouting at a member of staff before going round to the other side of the counter, whilst telling her to empty the contents of the till into his bag.
A second staff member came out from the back of the shop.
The man, who had a knife, told the members of staff to lay on the floor and he then fled the scene with around £180 in cash.
The two women were left shaken by the incident.
The man is described as white, aged in his mid 30s, wearing black tracksuit bottoms, a black coat with the hood up and white trainers.
He was carrying a black rucksack.
