SAN ANTONIO -

An arson investigation has been launched on San Antonio's West Side, where a vacant mobile home was destroyed by fire late Wednesday morning.

The mobile home, located in the 1700 block of Pinn Road, was fully engulfed in flames by the time firefighters arrived at 11 a.m.

Firefighters worked quickly to contain the flames and keep the fire from spreading to other nearby mobile homes.

Fire officials said the cause of the fire is unknown because utilities were not hooked up at the home.

No one was hurt.
