BAYONNE, N.J. (AP) — Authorities say a hoax threat against a school in New Mexico caused hundreds of parents to rush to a New Jersey school known by the same abbreviation.

The Jersey Journal reports that many parents of students at Bayonne High School picked up their children early on Friday after hearing of a social media post threatening "BHS students."

Police say the threat was made Wednesday by a 16-year-old student at Belen High School, about 30 miles (48 kilometers) south of Albuquerque. Authorities say he wanted "to see what kind of response he would get."

Police responded to the Bayonne school around 7:45 a.m. Friday. By about 10 a.m., they determined there was no threat.

The school says about 500 students were pulled out of school early.
