Does a Campus Police Officer Exceed His Authority by Arresting a Person Off Campus ?

In Commonwealth v. Savage, 403 Pa. Super. 446, 589 A.2d 696, 698 (Pa. Super. 1991), appeal denied, 529 Pa. 633, 600 A.2d 953 (1991), a campus police officer arrested defendant off campus for driving under the influence of alcohol. The officer apprehended the defendant after he had run a red light and had driven his truck the wrong way down a one-way street. Both of these traffic offenses took place on streets which were off campus. The Court held that the officer had exceeded his authority under 646 to arrest where he did.
