HAMILTON -- The Special Investigations Unit has been called in to probe the case of a man who was Tasered and suffered a broken jaw during an "interaction" with police in Hamilton.

The SIU says Hamilton police were called Saturday in regards to a 19-year-old man with a knife causing damage inside a residence on Glennie Ave.

The agency says two officers discharged Tasers and the male was arrested, then taken to hospital to be treated for a broken jaw.

Four investigators and two forensic investigators have been assigned to investigate the incident.

The SIU investigates all reports involving police and the public where there is death, serious injury or allegations of sexual assault.
