Raiders escaped with cash from an East Sussex video shop after threatening a female shop assistant.
Three men burst into Apollo Entertainment in High Street, Hailsham, at 9.40pm last night.
They threatened the female shop assistant before snatching some cash from the till and fleeing.
The shop worker, who is in her 20s, was today recovering at home. Police have appealed for witnesses.
Manager Ryan Courtney said: "The girl is fine but a little shocked. It appears as if they just came in, threatened the girl, stole some money and then left.
"I don't know too much about it. We are just helping police at the moment."
Three men were arrested shortly afterwards and were today in police custody facing questioning.
Anyone with information is asked to call Eastbourne CID on 0845 6070999.
