Fire investigators are looking into what started a fire in a motel room.

According to Robin McGill with the Corpus Christi Fire Department, the fire started around 5:30 a.m. on a bed at the Motel 6 on the 6300 block of Interstate 37 and Valero Way.

Luckily, the fire set off the sprinklers in the room. The sprinklers kept the fire contained to one room and put out the flames before they could spread to other rooms.

No one was injured.
