Investigators are asking for the public’s help in identifying a suspected arsonist who they say set fire to children’s clothing inside a crowded Walmart store near Bremerton.

The blaze caused an estimated $3 million in damage and endangered more than 300 people who were in the store at the time, Kitsap County sheriff’s officials said.

Crews responded to the blaze, in the 6700 block of State Route 303, at about 10:30 a.m. after receiving several calls about clothing on fire inside the store.

The blaze set off the sprinkler system, and employees took quick action to try and limit the spread of the flames. Firefighters also worked to contain the flames to the clothing section before extinguishing the fire.

There were no reports of injuries.

Sheriff’s officials say the suspect entered the store wearing dark cothing, changed clothes after the fire and rode away on a bicycle.

Anyone who recognizes the suspect or who knows of his whereabouts is urged to call Kitsap County Sheriff’s Detective T. Dobbins at (360) 509-1026 or at (360) 337-5614. They may also contact Detective Sgt. Birkenfeld at (360) 340-5647.
