A southwest Houston motorcycle shop caught fire Thursday.
Around 3:30 a.m., firefighters arrived at the Grand Prix Motorcycle Shop in the 8700 block of Richmond Avenue and Dunvale Road.
Fire officials said flames were coming from inside the building, so firefighters made a fast attack and broke through the front glass of the shop to gain access.
Authorities said the fire started on the showroom floor and was relatively minor.
Arson investigators said the fire appeared to be intentionally set.
The cause is not yet known.
No one was injured.
