For at least the seventh time since November, a portable toilet was set ablaze near Russian Hill in San Francisco this morning, according to the fire department.
The fire was reported at about 12:45 a.m. near the intersection of Union and Taylor streets and was nearly extinguished by the time firefighters arrived, according to a fire dispatcher.
An arson team was out to investigate the scene, the dispatcher said.
The fire department warned construction workers on Dec. 9 about an arsonist and asked them to keep the toilets locked and out in the open to prevent damage to surrounding objects.
They are also asked to report any suspicious activity to the police department at (415) 553-0123.
The fires have not injured anyone and remain under investigation.
