A Greenville man is jailed on $450 thousand bond after police accused him of making bomb threats that caused the evacuation of a school and a medical facility earlier this month.

Police arrested 50-year-old Joseph Dros at a Columbia Avenue home early Thursday after investigators say they linked him to phone calls made on Wednesday of last week to Greenville High School and the UMPC Horizon Wellness Center on Conneaut Lake Road.

Greenville-West Salem Police Sgt. Paul Molton tells 21 News that phoned in bomb threats prompted evacuations at both facilities.

Hempfield Township Police Chief Dave Morgan says that although Dros has not admitted making the threats the cell phone used to make the calls was recovered when Dros was arrested.

Dros was arraigned before a District Magistrate Thursday on three counts of making terroristic threats, three counts of making bomb threats, and two counts of using criminal use of a communications facility.

The suspect was taken to the Mercer County jail where he is being held on $450 thousand bond.

His next court hearing is scheduled for May 4.
