Police are calling it a new low.

A thief strolled into a Gloucester County church during Mass recently and stole a bag of valuables belonging to an altar server.

Authorities are sharing photos of their suspect on social media in hopes that someone can identify the culprit.

The incident happened around 10:50 a.m. on April 7, at St. Charles Borromeo Roman Catholic Church, on Stagecoach Road in Washington Township.

The suspect grabbed a brown satchel belonging to a church altar server. The bag contained credit cards, electronic devices and SD memory cards, police said.

One of the photos released by police shows the suspect carrying the satchel while walking away from the church. The gender of the suspect isn’t clear.

The thief, who wore a dark coat, dark shorts and white sunglasses, has a large tattoo on the front of the lower left leg.

While thefts of this sort usually occur in places like movie theaters or public spaces, it’s rare to see them in a house of worship, township police Capt. Kenneth Kennedy said.

“Typically, we don’t really see this at churches,” he said. "This is a little different.”

Anyone with information is asked to contact Detective Fred Volpe at 856-589-0330, ext. 1102, or fjvolpe@pd.twp.washington.nj.us.
