A man was taken into custody for allegedly setting fire to his room at a hotel in Riverside.

Firefighters were sent to the Hyatt Place hotel at 3500 Market St. at 10:09 p.m. Monday regarding “reports of (an) occupant in a hotel room trying to burn down his room he was occupying,” the City of Riverside Fire Department said in a statement.

“Firefighters arrived to find the hotel being evacuated, light smoke on the second floor and the hotel room door locked with a fire sprinkler activation,” the statement said.

“The environment was safe for RPD officers to assist firefighters with opening the door and securing the hotel room. Firefighters discovered a small fire in the hotel room extinguished by the fire sprinkler system.”

The suspect was not in the room but was found in the building and detained by Riverside police officers. His name was not immediately released.

Firefighters assisted hotel staff with water removal from several hotel rooms and a hallway. Four hotel rooms were affected by the water from the fire sprinkler system. Damage was estimated at $100,000, the fire department reported.

About 50 occupants were evacuated from the structure but were allowed to re-occupy their rooms by about 11 p.m., the fire department reported. Hotel management accommodated occupants who were displaced by the water damage to other unoccupied hotel rooms.

City of Riverside Fire Department Arson Investigators responded to the scene and working with RPD conducted an investigation that is still ongoing.

There were no injuries.
