GREENSBURG, Pa. (AP) - A mall in western Pennsylvania has been evacuated after police believed an escaped jail inmate from Ohio was in the vicinity.

Shoppers at the Westmoreland Mall outside Greensburg were told to leave and the mall was placed on lockdown Sunday afternoon.

Pennsylvania state police tweeted that 24-year-old Christopher Clemente, an escapee from the Gallia County Jail in Ohio, is believed to be in the area.

They're telling shoppers and residents to lock their doors and make sure they don't leave car keys in their cars.

A news release from the Gallia County sheriff's office says Clemente was among four inmates who overpowered two guards early Sunday morning and escaped.

The four are considered extremely dangerous.
