Police activity around midday Friday closed off access to Phillipsburg High School.

Police cars from both Phillipsburg and Lopatcong blocked the entrance to the school, though it was unclear as of 1 p.m. what prompted the response to the school in Lopatcong Township.

Police and school officials could not immediately provide more information, though New Jersey State Police at the Washington station confirmed they were assisting. Lopatcong police said more information may be released this afternoon.

Almost two months ago, a threat scrawled on a bathroom wall resulted in a similar police response.
