MARTINSVILLE, Va. -A second man has been arrested and charged with making a bomb threat at the Martinsville Walmart last Sunday.

Authorities responded to the store around 2:30 Sunday afternoon after the threat was received. K9 units officers from multiple agencies searched the store and grounds but no bomb was found.

Investigators believe 18-year-old Keegan Blaise Ashbrook and Ricky Lee Stout, 36, headed to the Walmart together. Deputies say Walmart staff detained Ashbrook for shoplifting. Moments later, a store employee received the bomb threat.

Authorities believe Stout made the call to help Ashbrook avoid arrest. Ashbrook is charged with shoplifting and possession of a concealed weapon. He has since been released on bond.

Stout was arrested on Tuesday and charged with threatening to bomb a building, a felony. He is being held in the Franklin County Jail on a secured bond.

The Henry County Sheriff’s Office is handling the investigation.
