The 18-year-old Anderson County man accused of robbing his grandfather with the help of a second man armed with a knife was arrested Tuesday, authorities said.

Joseph Tyler Collins has been charged with aggravated robbery and is being held in the Anderson County Detention Facility in Clinton, said Mark Lucas, Anderson County Sheriff’s Department chief deputy. Collins’ bond has been set at $75,000.

Collins’ grandfather, Genis Hawkins, reported that he was robbed at knifepoint by his grandson and the second unidentified man, who was wearing a green rag over his face and holding a 15-inch-long knife, on November 20. Collins was arrested at a Clinton home on Tuesday afternoon.

Lucas said Sheriff’s Department investigators are still working to identify the others involved in the robbery. [Read more…]
