(Reuters) – Law enforcement officials searched on Monday for an escaped prisoner on the loose in northern Alabama following a jailbreak of 12 prisoners, the local sheriff’s office said.

There were scant details about how the 12 inmates managed to escape from Walker County Jail, northwest of Birmingham, but the county sheriff’s office said on Facebook that authorities had recaptured 11 of them, some at a highway truck stop.

They continued to hunt for Brady Kilpatrick, the 24-year-old inmate who was still at large. Kilpatrick had been in jail facing charges of marijuana possession.

Police in the small city of Jasper, where the jail is located, urged downtown residents to stay inside and turn on their outdoor lights. Police from nearby Parrish, Alabama, were also involved in the search.

The dozen escapees, all men aged 18 to 30, were imprisoned on charges including robbery, attempted murder, domestic violence and drug possession.
