Armed robbery at Derby fast food outlet
Two masked men armed with a gun and a knife broke into a fast food restaurant and locked up three members of staff before escaping with cash.
The men, wearing balaclavas, entered Burger King on Wyvern Way, Derby, on Thursday night as staff were closing up for the night.
They threatened the workers and locked them in an office before escaping with an undisclosed amount of cash.
Staff were freed shortly after raising the alarm, police said.
The robbers made their getaway along Chequers Road.
