The same burglar stole cash twice in one week from the same Rockville Centre church while it was closed, Nassau police said.
The first time the suspect pried open a donation box at St. Agnes Cathedral was on Aug. 20 at about 5:30 p.m., police said.
Seven days later, police said the same man got through a locked gate, entered the main area, and again broke into a donation box, this time at about 4:30 p.m.
Police, who did not say how much cash was stolen, described the burglar as a thin man who stands about 5-foot-8 to 5-foot-9 and has medium-length brown hair.
During one of the break-ins, he wore a purple T-shirt and light sweatpants with black sneakers. During the other, he was clad in a red T-shirt and black sweatpants with black sneakers, police said.
