The FBI has provided details to the public on how they can retrieve their vehicles from the outlet mall.

Those with vehicles that were left at the mall can meet at the Allen Senior Recreation Center beginning at 5:45 p.m. local time Sunday, where they will be sent to the outlet mall, the FBI said Sunday in a press release.

The senior center will be managing the retrievals until 9:30 p.m. local time, the FBI said.

"Please drop off only one individual for vehicle retrieval," the FBI said. "Be sure to have your car keys with you."

Officials have urged the public not to go directly to Allen Premium Outlets.
