HOODED robbers stole £400 from a convenience store after attacking staff and ordering them to hand over cash.
Police are investigating the robbery at Londis in Chipstead Valley Road, Coulsdon, last Tuesday, January 7.
The shop was open and a member of staff and a co-owner were inside when the two robbers burst in just before 7pm.
One jumped over the counter to take cash and a packet of cigarettes while the other grabbed a member of staff.
The co-owner of the store, who did not want to be identified, said she was pushed to the floor.
She added: "They came in – one of them looked like he was 16 or 17 and the other must have been a bit older.
"One held the guy doing the hoovering and one jumped up the counter.
"I hit the panic button. It does not make noise outside but at the police station.
"We have been here nearly 30 years.
"It is the first time this has happened.
"You don't expect them to jump the counter."
The shop remained open afterwards and CCTV footage is currently being reviewed.
Police are appealing for witnesses or anyone with information to come forward.
A Met police spokesman said: "We can confirm that police are investigating a robbery at a convenience store in Chipstead Valley Road on January 7.
