Police in Yonkers, N.Y., are looking for three men who attempted to rob a Lord & Taylor department store Wednesday morning.

The men, wearing white masks, walked into the store shortly after 6 a.m. and smashed glass jewelry cases, but left before they could take anything, according to lohud.com.

They were wearing all black, police told lohud.

Police are searching for the suspects.

Shoppers and workers at the mall were shaken by the break-in.

Ashley Delgado, a waitress at a restaurant opening in the mall later this month, said she and her coworkers will "definitely be walking to our cars in twos and threes."
