SAN ANTONIO – San Antonio fire investigators are trying to determine who started a fire at a North Side building by hurling a Molotov cocktail at a ground-floor office window.
Firefighters were called around 12 a.m. Monday to the building in the 7400 block of Blanco Road.
They found damage to a window of the ground-floor office and inside the office.
A San Antonio Fire Department spokesman said the fire already was out and that firefighters found mostly smoke when they arrived.
No one was inside the office, which was closed at the time.
An employee later told KSAT 12 News it was home to an engineering firm.
It's still unclear if the Molotov cocktail was meant for someone in particular or if the incident was a random act of vandalism.
The damage is estimated at about $5,000.
