An arson investigation is underway in Oakland after a massive Christmas tree in Jack London Square was set on fire, the fire department said Monday.
The fire department said one or more people set the 52-foot tree on fire during the overnight hours.
"It sounds like surveillance in that area is quite strong so hopefully it should not take so long to determine what direction he may have come from or who may have been involved," said Michael Hunt of the Oakland Fire Department.
Firefighters were able to contain the blaze, but there was some noticeable damage.
A Dec. 11 tree lighting is still on schedule, the fire department said, citing the organizers.
