EVANSTON, Ill. (STMW) – Fire investigators suspect arson as the cause of a Monday blaze that ripped through a north suburban Evanston duplex, causing about $150,000 in damage.

The fire department received several reports about 2 p.m. of a fire at 1813 Lyons St. in Evanston, said Evanston Fire Division Chief Thomas Janetske.

He said when firefighters arrived, heavy smoke was reported from the second floor windows and firefighters entered the duplex to contain the blaze.

Everyone was out of the house by the time firefighters arrived and there were no injuries, Janetske said.

Janetske said fire damage was contained to the second floor, but caused an estimated $150,000 damage to the structure.

He said fire officials suspect arson, but declined to say what about the fire led them to believe it was intentionally set. Fire Chief Greg Klaiber could not be reached for comment Monday night.

Janetske said investigators are talking to several people at this time, but there have been no arrests.

Officials also suspect arson for a Christmas Day fire in the 1800 block of Laurel Avenue in Evanston.
