A fire broke out at a vacant commercial building in Milford early Tuesday morning.

According to officials, just before 3:00 a.m., dispatchers received a call reporting a fire in a building located at 1469 Boston Post Road.

The structure was formerly the site of the Loading Dock Liquor store.

Fire crews arrived and became concerned about homeless occupants possibly being trapped inside. After an aggressive search effort, firefighters deployed multiple hose lines and controlled the blaze within 40 minutes.

Officials did not say if anyone was inside of the structure when the flames broke out.

The cause of the fire is not known at this time.
