(AP) — Federal agents searched the home of Atlantic City Mayor Frank Gilliam Jr. on Monday, but authorities and the mayor himself were tight-lipped about what prompted the raid.

Agents in dark blue FBI windbreakers carried white cardboard boxes out of the house, which is about a mile from Atlantic City’s casinos. Earlier they removed a computer and a printer, stashing the items in dark sport utility vehicles.

Outside the home, FBI agent Jessica Weisman said, “We are here in an official capacity, executing a search warrant. That’s all we can say.”

Gilliam emerged from the home shortly after 12:30, ignoring shouted questions from reporters. He then got into his personal sport utility vehicle and drove away.

A spokeswoman for the mayor’s office said it remained open Monday, though Gilliam was not there.
