UNIONTOWN, Pa. (AP) -- A county detective says a man serving six months in a southwestern Pennsylvania county jail illegally hid a cellphone and charger in his prosthetic leg.

Twenty-seven-year-old Christopher Greer, of Uniontown, faces a preliminary hearing May 22 on a contraband charge filed last week by a Fayette County detective.

The detective says the phone was found during a search of Greer's cell on Feb. 23.

Greer was sentenced to jail after he was convicted in March of driving with a suspended license. Inmates are not allowed to bring their own phones into the jail.

Greer's public defender did not immediately return a call for comment Monday.

The Fayette County Prison is about 40 miles south of Pittsburgh.
