Sama Varanand was closing the Green Wrythe Lane restaurant at about 11:30pm. Friday, when two men forced their way into the shop and held five staff, including teenagers, at gun point.

The robbers demanded money from the safe and when they were unsuccessful they confiscated staff members phones to stop them calling police and barricaded them in the toilet before fleeing with some cash.

CCTV of the robbery shows the robbers frisking terrified delivery drivers.

The whole ordeal lasted about 20 minutes.

Mr Varanand said: “I was at the front table and the other staff were at back, they asked me to sit down and one guy stayed with me while the other went to the back of the store.

“I thought someone was playing a joke at first, I didn’t think they were robbers.

“They brought my colleagues to the front of the shop and held a gun to one of their heads to ask for the safe password but he didn’t tell them.

“Then they hid our phones in the shop and locked all of us in the toilets.

“The staff were scared so badly, it is so scary, you know, there is a knife and a gun involved.

“Two of the staff were crying.

“I have never seen anything like this before in my life and I hope I never do again.”

Mr Varanand said as soon as he knew the robbers were out of the shop, staff fled out the back exit and called police when they knew they were safe.

Two days later the store was the target of another robbery. This time the front door was smashed in an several delivery bikes were stolen.

The Metropolitan Police flying squad is investigating and no arrests have been made.

No one was injured during the robbery.
