Police said the robbery attempt caused panic because of the sound of shattering glass. Another similar incident happened at the Modesto Mall Sunday, but the Milpitas Police Captain Raj Maharaj would not confirm if the two incidents are related.

Police are searching for three suspects who are still at large, saying they may have escaped the scene in a black sedan.

Police are advising people to stay clear of the area. Officers began escorting store employees and shoppers inside the mall outside to parking lots while the investigation continued.
