After an unexpected guest - a black bear - caused alarm Friday when it was spotted in the Wissahickon Creek in Fairmount Park, park-goers were left wondering: What happened to the animal?

The bear swam across the creek and disappeared into the woods after a crowd gathered along the bank. It's not known where it went after that.

No black bear sightings were reported in the Wissahickon over the weekend, Erin Mooney, a publicist for the group Friends of the Wissahickon, said Monday.

"All we know is there was a bear in the Wissahickon," she said.

Officials don't know where the animal came from or where it is now.

"We wish the bear well and hope it's safe," Mooney said.

Officials from the Pennsylvania Game Commission searched the area where the bear was spotted, near the Valley Green Inn, but called off efforts to find it later Friday.

Mooney said a black bear was seen in Tredyffrin Township in Chester County, about 12 miles from the park, on Sunday, but it wasn't known whether it was the same animal.

In the meantime, park users should stay alert, keep pets on leashes, and report any sightings by calling the Game Commission at 610-926-3136 or 911.
