A fast-moving four-alarm fire swept through a clothing store in Roxbury’s Dudley Square during Tuesday evening’s rush hour, causing $300,000 worth of damage, a fire official said.

The fire was reported at about 5:45 p.m. at Nikki’s Fashion, located at 2365 Washington St., said Boston fire spokesman Steve MacDonald at the scene.

No injuries were reported.

The fire was caused by an electric short-circuit in a baseboard heater, MacDonald said late Tuesday night.

Heavy smoke and fire could be seen from the roof as dozens of firefighters attacked both the rear and front of the squat, brick, v-shaped building, said MacDonald.

The clothing store was sandwiched between a liquor store and a three-story building that included offices, which were safely evacuated.

The clothing store is across the street from the Dudley MBTA station. Silver Line buses were detoured onto Dudley Street, according to the T.

Traffic was heavy in Dudley Square at the time of the fire, said MacDonald. Several streets were closed to traffic in the square area, snarling traffic further.

The fire is believed to have started in the rear of the clothing store, the spokesman said. It crept up a wall of the building and across the ceiling, eventually working its way up through the rubber roof of the structure, he said.

The building was not in danger of collapse, he said.

The nearby liquor store suffered minor smoke damage, while the three-story building suffered minor damage as firefighters used it to battle the fire in the clothing store, MacDonald said.

Most of the fire was knocked down within about 30 minutes, said MacDonald.

About 90 firefighters responded to the blaze.

The store was closed when the fire started, said MacDonald. Firefighters had to break into the building to gain access, using saws to cut through metal grates in the front and rear of the building.

The interior of the clothing store appeared to be blackened and charred Thursday night as firefighters walked through the wreckage of the blaze shortly after 7 p.m.

Tuesday’s blaze marked the second fire in Boston to reach at least four alarms in recent days. Late Saturday night, a five-alarm fire badly damaged a three decker on Allston Street in Dorchester, displacing 14 people.

The cause of that fire has yet to be determined, MacDonald said Tuesday night.
