A US man has been arrested by police after allegedly choking his girlfriend with his dreadlocks.

Caleb Grotberg's partner told police officers he assaulted her in their own home before trying to wrap coils of his long locks around her neck in an attempt to strangle her.

Police say she was taken to hospital for treatment of numerous non-life threatening injuries.

The long-maned attacker was located by police near his home shortly after the alleged attack and was taken into custody.

According to reports, Grotberg is facing several domestic violence felony crimes, including strangulation, fourth-degree assault and second-degree kidnapping.
