ST. PAUL (AP) - Police say robbers have taken about $300,000 in Rolex watches from a St. Paul jewelry store while it was open.

St. Paul police on Tuesday released surveillance video of the robbery over the weekend at R.F. Moeller Jeweler in the Highland Park neighborhood. A police spokesman says two men hold open doors to the business while two others used hammers to smash glass display cases and grab about 30 watches before fleeing. He says no one was hurt.

The video shows the men walking into the store and pulling out hammers from the waist of their pants. Several employees can be seen in the video. Another man who appears to be a customer walks through the store after the robbery and appears to be unaware of what just occurred.

No arrests have been made.
