Fresno police arrested a teenager suspected of setting fire to the Bond Street Market on Belmont last month.
Police have surveillance video they say is the teen and a fellow gang member tossing gas on the building before setting it on fire.
Police are still looking for 19-year-old Christopher Rocca, who is a "person of interest" in the same arson fire.
Anyone with information about Rocca is asked to contact the Fresno Police Department.
