Three units were damaged in an electrical fire that started in a Fredericton apartment building late on Thursday evening.

Platoon Capt. Jeff Mills said the fire at 490 Regent Street was called into the Fredericton Fire Department at 11:30 p.m.

When firefighters arrived, flames were visible on the second and third floors. He said the fire was moving up the exterior of the building.

Mills said there was damage done to units on three floors of the four-storey building.

However, he said the fire is not being considered suspicious.

Tenants of the three damaged units were not able to return, while the building's other residents were allowed to back inside at 2 a.m.

Two city buses were brought in for shelter for the residents while they waited to return to their apartments.

As well, the nearby Harvey’s also welcomed residents into the restaurant while they waited.
