Black bear crashes Lehigh University party, gets collared

BETHLEHEM, Pennsylvania – A college party got a little wild when a black bear showed up.

The black bear, weighing between 300 and 400 pounds, crashed the party early Saturday near the campus of Lehigh University.

Emergency officials received a flood of emergency calls after the bear was spotted around 2 a.m. in south Bethlehem, about 50 miles north of Philadelphia.

The bear “lumbered close to the party and scared the living daylights out of people,” police Chief Mark DiLuzio said.

Lehigh University said in a “Bear Update” on its website that the animal was captured, tranquilized and removed from the area a couple of hours later.

DiLuzio said the same bear was seen Friday near an arena and the university’s athletic facilities, but it ran away into a swampy area.

Tyler Krieder, district officer of the Pennsylvania Game Commission, said a tattoo on the bear’s inner lip indicates that it was from New Jersey. Noting that bears are good swimmers, he theorized that the animal swam across the Delaware River to find a new home.
