A man stealing a gallon of sealant from a Charleston home improvement store tried stabbing an employee who was trying to stop the theft, according to police.

Gerald Edwards, 45, of Charleston, was charged with armed robbery and possession of a knife during a violent crime. Police said Edwards was attempting to steal a gallon container of surface sealer, valued at $89.97, from the Home Depot on Magwood Drive on Friday at 1:30 p.m. A loss prevention employee at the store tried stopping Edwards by attempting to detain him, an incident report stated.

Edwards pulled out a four to six inch knife and raised it above his head, the report stated.

Edwards told the employee "Get off me or I'll stab you," according to the report. He then attempted to stab the employee, police said.

The employee pushed Edwards off of him and Edwards ran off, according to the report. The store employee told police Edwards had stolen the same type of item on Dec. 2 and immediately tried to return the sealer for cash at the North Charleston Home Depot, the report stated.

North Charleston Police checked the Northwoods Boulevard store to see if Edwards was on site and found him in his vehicle in the store parking lot, according to police. Police arrested Edwards and a magistrate judge set a $200,000 bail for the charges against him.
