Investigators searching for arson suspect who lit several fires in Riverside

Authorities are searching for an arson suspect who they believe is responsible for starting several fires in Riverside on Friday. 

Three different brush fires were reported at around 10:15 p.m., but Riverside Fire Department crews that they actually found seven different fires burning in the area near American Legion Riverside Post 79 at Lake Evans to Mission Inn Avenue, according to department officials. 

"As the first due engine made entry on to the Santa Ana River Trail, the company officer was notified by bystanders that a homeless person wrapped in a blanket was lighting the fires," said a Facebook post from the department. 

Arson investigators were called to the scene to assist with the investigation. 

In total, the fires burned just over an acre of vegetation in the area before crews were able to contain the flames. 

Despite also receiving assistance from Riverside Police Department helicopter Air One helping with reconnaissance, they were unable to locate the suspect. 

Investigators said they would return to the area in the next few days as their probe continued. 

No injuries were reported in any of the fires and no structures were damaged.
