A full investigation is underway at Apponequet Regional High School, looking to find out who wrote apparent bomb threats on bathroom walls.

Students were evacuated and dismissed early from school today, after two messages were found written on the men's room stall after 10am this morning.

Several callers to FUN 107 claim the messages said "I have C4 and I hate this school".

Superintendent Dr. Jessica Huizenga tells WBSM News both internal and external personnel are looking for the responsible parties.

Huizenga says a seperate threat was also found Tuesday night, again on the men's bathroom stall.

Bomb squads were called in on both occasions, finding no credible threats.

Lakeville Police are offering up to $5,000 for information leading to the arrest of the culprit(s).
