SAN ANTONIO -

San Antonio firefighters battled a fire early Wednesday morning at a Northwest Side auto customization shop.

Police were initially called out for an alarm intrusion at Addiction Offroad & Performance in the 5500 block of Timberhill Drive around 4:30 a.m.

Officers said they found one of the doors open and the fire in an office area. The fire department responded and quickly put out the fire.

The owner tells KSAT the open door was on a vacant building next door and it looks like the fire may be electrical.

He also added no vehicles were damaged, including a $250,000 customized Ford King Ranch that he was working on.

Damages were estimated at $10,000. The San Antonio Fire Department has not released an officials cause for the fire.
