A Key Biscayne fire fighter was released after being hospitalized following an early morning blaze inside a strip mall.

Officials say the fire broke out inside the complex at 951 Crandon Boulevard before 1:30 a.m., saying it appears to have started as an electrical issue above two units. A total of six units were damaged by fire on the roof, smoke or water as a result.

Nearly three dozen firefighters responded to deal with the blaze, with one being taken to Ryder Trauma Center with minor, undisclosed injuries and later released.
