AUSTIN (AP) — Gun-rights groups that planned to stage a mock shooting at the University of Texas are moving their event off-campus after getting a warning from the school.

The groups Come and Take It Texas and Dontcomply.com announced plans for the Saturday event that would include cardboard guns and fake blood.

The university issued a statement Wednesday warning that the Austin campus isn’t open to outside groups staging demonstrations. The university says violators could face criminal trespassing charges.

The groups then said they would move their demonstration to an area next to campus.

Organizers say the purpose is to rally support for gun rights.

University officials say they support free speech but that they routinely bar outside groups from demonstrating on campus.
