A 21-year-old West Australian man has allegedly used a chainsaw in an attack against another man, cutting through a chair and lacerating the victim's arm.
Police say the attacker was involved in an altercation with a 30-year-old man at a hotel in Northam, 97km northeast of Perth, about 12.10am today (local time).
The 21-year-old man allegedly threatened the victim with a knife and threw a glass at other people in the hotel.
He then entered a storage area and armed himself with a chainsaw before threatening the victim who was holding a chair.
The man allegedly started the chainsaw and cut through the chair, making contact with the victim's arm.
The victim received a deep laceration to his arm and was taken to Northam Hospital by ambulance, but his injuries were not considered life-threatening.
The 21-year-old man has been charged with acts intended to cause grievous bodily harm and will appear in Perth Magistrates Court on Monday.
