A young woman known to police has been charged after officers responded to a west-end residence Wednesday afternoon.

Kingston Police were called to the residence at approximately 3:30 p.m. by a male victim who had locked himself in a room to escape the accused, said Const. Steve Koopman. The 21-year-old man was hiding from his girlfriend who police say had threatened him with a knife.

The altercation started when the couple, who lived together, got into an argument about possibly separating. The woman struck the man, who then called 911 and left the room to pack up his belongings. The accused followed him and threw three coffee mugs, striking the victim twice. The woman then grabbed a kitchen knife and threatened to stab the victim, Koopman said.

A 21-year-old Kingston woman has been charged by police with assault, assault with a weapon, threatening to use a weapon, uttering threats, and weapons dangerous. She was held overnight to face a bail hearing on Thursday.
