REHOBOTH (CBS) — A 911 call about “‘white smoke’ coming from the gas pumps” led members of the Rebohoth Fire Department to a Cumberland Farms on Monday afternoon.

When they got there, officials discovered the Winthrop Street gas station’s fire suppression system had gone off around 12:45 p.m.

What firefighters did not find, though, was a fire.

The cause of the system malfunction was not determined.

A fire official told WBZ-TV it is not uncommon for heat to set off the system.

Several people that had been near in the close vicinity of the system were taken to a local hospital, said Rehoboth FD.

How many people and the extent of their injuries are unknown at this time.

Monday’s incident was at the same Cumberland Farms that police were called to in September of last year after a man threatened the store clerk. A four-hour police standoff ensued.
