Investigators with the Fairfax County Fire and Rescue Department are still looking into the origin and cause of a three-alarm fire that caused an estimated $600,000 in damage to a vacant restaurant in the Brookfield Plaza Shopping Center July 7.

There was fire visible coming from the roof and smoke from the front and rear of the restaurant when firefighters responded around 2:18 p.m.

Seventy-five firefighters were called in total, due to the size and heat of the fire. That included aid from the Arlington County Fire and Rescue Department, Alexandria Fire Department and Fort Belvoir Fire Department.

The combined forces had the fire under control in around 50 minutes, a release said. There were no injuries to any firefighters or civilians.
