EDISON, NJ - Detectives from the Middlesex County Prosecutor's Office and the township Police Department are investigating a second suspicious fire, once again set in a boys' lavatory, but this time at the Lindeneau Elementary School.

A staff member at the Blossom Street school quickly extinguished the 10:06 a.m. bathroom fire after being alerted by a student and smelling smoke. Similar to a July 17 bathroom fire at the Washington Elementary School, police said that paper products, including toilet paper rolls, were allegedly ignited.

Students were evacuated as a precaution after Tuesday’s fire at Lindeneau. They are the same 120 youngsters, from grades 1-4, who until last week attended a summer literacy program at the Washington School, district officials said.

Township firefighters responded to Lindeneau to assess the damage and to ensure the fire had been completely extinguished. The Lindeneau school, like Washington Elementary, is equipped with smoke detectors and alarms, but the fire did not burn long enough to activate them, school officials said.
