Temple University is expanding the patrol zone for its campus police force.

The North Philadelphia school announced today that the western boundary of the patrol area for its officers has been extended to 18th street.

Temple previously listed 16th Street as the western end of its police patrol zone.

The university said in a statement that the extension was made "to further improve responsiveness to Temple's off-campus residential student population and community members who live near Main Campus."

The patrol area now runs between 18th and 9th streets, and from Susquehanna Avenue at the northern end to Jefferson Street at the south.

Temple said the extended area started in August as a pilot program and is fully taking effect as the academic year begins.

Both Temple's about 130 sworn officers and 250 full-time full-time AlliedBarton security guards will patrol the extended zone, including some on bicycles.

"Having more clearly defined and extended borders responds to the growth in Temple's residential student population, especially west of Broad Street,"  Charles J. Leone, executive director of Campus Safety Services, said in the university's statement. "This decision also follows productive discussions in the spring among students, parents, faculty, staff and local residents about ways in which security initiatives could be further improved."

This spring, Temple warned the university community about several attacks on students in the area of North 17th Street, just west of the university -- which at the time was not included in campus police patrol zone, but is part of the extended area.

Those incidents included a violent assault in which a student was struck in the face with a brick.

The Temple News reported this spring that discussions about expanding the range for campus officers were taking place in the wake of those attacks.
