An inmate who escaped from a prison in Western Pennsylvania in early December has been captured after authorities found him leaving a Planet Fitness in Philadelphia.

Isaiah Robert Tilghman, 33, was taken into custody Friday in the 3300 block of Aramingo Avenue in Philadelphia, the U.S. Marshals Service Philadelphia said.

Tilghman had escaped from the Blair County Prison on Dec. 3 after he was arrested on drug charges and parole violations. After his escape, Tilghman stole a red 2011 Ford F-150.

The prison is about 200 miles west of Philadelphia, where the escapee was spotted Friday morning on the 1800 block of East Schiller Street in Kensington, FOX29 Philadelphia reported.

"This arrest was a result of Fugitive Task Forces in Philadelphia and Pittsburgh, diligently working together, to capture a dangerous escapee," U.S. Marshals Deputy Robert Clark said. "The Marshals Service is unequivocally the best in the business at finding people who do not wish to be found, and this arrest reinforces that fact."

Tilghman was charged with escape, flight to avoid apprehension and additional charges relating to the escape.
