RADNOR, Pa. (CBS) – Police are searching for four to six men who robbed a jewelry store on the Main Line on Wednesday night.

Around 4:40 p.m., the suspects robbed the Bernie Robbins Fine Jewelry Store on East Lancaster Avenue at gunpoint. They reportedly entered the store, smashed out several jewelry cases, and removed an undetermined amount of jewelry from the store.

All of the subjects appeared to be black males, and all but one wore some type of covering over the lower part of their faces. The subject without a covering is described as a thin, light-skinned black male with very short hair.

Bernie Robbins is offering a $5000 reward for information leading to the arrest and conviction of anyone responsible for the crime.
