Toronto police say a man trying to show off his gun at a party in North York on Thursday night accidentally shot a woman.

Police tell the Toronto Sun the 18-year-old victim initially told them a fake story about being robbed, but the investigation revealed the shooting actually happened at a party.

The woman was taken to hospital with a gunshot wound to her arm.

Police arrested a man in connection with the shooting, and he was charged with aggravated assault and several gun-related offences.
