ABILENE, Texas -

A suspected shoplifter is facing more serious charges after flashing a knife at Walmart employees.

About 9:15 p.m. Tuesday, police say employees at the north Abilene Walmart stopped 33-year-old Joshua David Patton just outside the store when they suspected him of shoplifting.

The police report indicates Patton flashed a knife at employees so they backed off and called authorities.  They were able to give police a description of the vehicle he was driving and police stopped his car near Ambler and North Judge Ely.

Patton has been charged with aggravated robbery because of his use of a knife.
