Early morning dumpster fires in Union Square investigated as arsons

Dumpsters in Union Square were set aflame early Friday morning by an unknown arsonist, police said.

San Francisco firefighters snuffed out the first dumpster fire around 12:20 a.m. on the first block of O’Farrell Street near Stockton Street, police said.

Then about 15 minutes later, a second blaze was ignited inside a dumpster a block away on Geary Street near Stockton Street, police said. Firefighters put out the flames, which were still burning when they arrived at 12:37 a.m.

No witnesses were found in either dumpster fires and no arrests were made. It’s unclear if the two fires are connected, or how many people were involved.

Across The City in Hunter’s Point, a silver Lexus was burned around 4:15 a.m. on Kirkwood Avenue and Nautilus Court, police said. The Fire Department later determined the destruction of the four-door sedan was the work of an arsonist.
