A threat has prompted district officials to cancel classes at all Allen Park Public Schools on Thursday as a precaution.

The message, which indicated violence against an unspecified school, was found on a restroom wall, Superintendent Michael Darga said in a statement. The statement did not indicate in what school the message was found.

“School officials are working with law enforcement on an investigation,” he said. “Those responsible will face the appropriate consequences.”

The superintendent did not release other details but reminded parents and students about the state’s OK2SAY tip line. The safety program launched in 2014 received a record 980 tips in March, including 131 planned school attacks, Attorney General Bill Schuette’s office announced last week.

A record number of tips also was received in February, the same month a Parkland, Florida, high school shooting left 17 people dead and 16 wounded.

Since that incident, authorities and school districts across southeast Michigan have addressed scores of threats — resulting in closures, lockdowns and charges for some youths.
