Langley RCMP have released a composite sketch and two surveillance camera images in an attempt to track down two suspects in a robbery earlier this month.

Police say two Indo-Canadian men entered a Telus Store in the 20200-block of 66th Avenue just past 7 p.m. on March 3.

One of the men asked a female employee to see a phone, and as she went to retrieve it he pulled out a knife.

The suspects then stole several cell phones -- including an undisclosed number of Apple iPhones -- and Bluetooth devices before fleeing the store.

The total value of the products stolen has not been released, but Cpl. Holly Marks said it is substantial.

"They got several devices, and of course an iPhone is worth about $500," she said.

Police are asking anyone who recognizes the suspects to contact the Langley RCMP at 604-532-3200 or Crime Stoppers at 1-800-222-8477.
