Four non-student teenagers were arrested on trespassing charges today after they entered Red Bank Regional High with the intent of setting a gripe with a student, Little Silver police said.

No weapons were involved, no one was injured, according to police.

The Asbury Park Press reports that an RBR student mistakenly allowed the four into the locked building’s cafeteria late this morning.

Police said three of the unwelcome visitors entered the building at about 11a while a fourth waited in a car outside.

The three were immediately recognized by Principal Jim Stefankiewicz as non-students; he and another staffer detained two of them while Ptl. Pete Gibson, who works at the school as a resource officer, went after the third, who had fled on foot through the cafeteria.

Gibson caught the supect after a brief chase, police said.

The fourth suspect was apprehended as he waited in the vehicle outside.

An investigation revealed that the four were planning to confront an RBR student over a “personal matter,” police said in a statement.

Charged with trespassing were Carlson Fischeick, 19; Vincent Kennedy, 18; and Michael Teti, 19, all of Long Branch; and James Roman, 19, of Bradley Beach.

Police from Little Silver, Fair Haven and Rumson responded.
