A nude man running west along Columbia Avenue on Sunday has a mental illness, according to a woman who called the newspaper identifying herself as his sister.

At least several people saw the man running around 12:30 p.m. in East and West Hempfield townships.

One of the people who saw him was Holly Love, an FM 92.7 air personality.

She was on her way to a children's birthday party with a friend, her son, Peter, 9, and daughter Mia, 4, when they saw the man about 12:30 p.m.

At first, Love thought perhaps the man was wearing a skin-toned outfit.

She and other called police. Love said she looped around the block and by then, two squad cars had arrived.

Phone messages left for West Hempfield police weren't immediately returned Monday morning.
