Fires determined to be arson were set in the Mission, SoMa and Tenderloin neighborhoods, according to police. All three small fires were quickly extinguished.
The first fire started around 1 p.m., when a passenger exiting Muni in the Tenderloin threw something into a trashcan, setting it on fire.
The second fire was spotted in a garbage can around 5:30 p.m. near Van Ness and Market streets, according to SFPD.
Police were alerted to the final fire just after midnight. Debris had been set against a building and then ignited, police said.
The police continue to search for a suspected arsonist who is believed to have set several fires in SoMa. Images and video of the suspect were released by SFPD yesterday.
