Derry shop worker threatened in robbery

A shop worker has been threatened by a man armed with a hammer during a robbery in Londonderry.

It happened on Carlisle Road at about 20.30 GMT on Monday.

The woman was left badly shaken after she was confronted by two men.

They escaped with a sum of money.

Shop owner Brian Warke said he didn't know when the teenage shop assistant would be able to return to work.

"She is very upset and this will leave emotional scars," he said.

"The police will be reviewing the CCTV footage and hopefully someone will be caught."
