Charleston police arrested a man accused of using a stun gun on his ex-girlfriend during an altercation.

Christian Robinson, 26, of Devereaux Avenue, was charged with first-degree assault and battery and first-degree burglary in connection with the incident, police said.

Charleston police were dispatched to an apartment on Camp Road about 3:30 a.m. Monday concerning a dispute involving weapons.

A 19-year-old woman who lives at the apartment told police that she was sitting in her bedroom when Robinson loudly banged on her window and yelled that he was going to kill her.

Robinson entered the apartment through an unlocked sliding-glass door and the pair began pushing and shoving one another, an incident report states.

Then, the woman told police, Robinson used a stun gun against her left shoulder.

A 22-year-old man who was also at the apartment beat Robinson on the back with the butt of an unloaded rifle and chased him out of the apartment, the report states.

Charleston County Sheriff’s deputies who assisted in the case found Robinson at the front of the apartment complex, the report states. Deputies also found a stun gun hidden in some bushes nearby, police said.

Robinson was held at the Charleston County jail pending a total $100,000 bail, jail records show.
