Sacramento and West Sacramento firefighters responded to a string of set brush fires Saturday evening along the bike trail.
The fires were located near Jibboom Street between the I Street bridge and Discovery Park.
The blazes were quickly contained but kept fire crews busy chasing the string of fires.
There is no description of the arsonist at this point said Craig Weidenhoeft, Battalion Chief, Sacramento Fire Department. Weidenhoeft and fire crews patrolled the area for additional fire starts; none were found.
