Three Toronto police officers have been charged with assault causing bodily harm following a probe into a 2013 arrest that landed a man in hospital with a "serious injury," the Special Investigations Unit announced Tuesday.

The three officers — Const. John Darnell, Const. Piara Dhaliwal and Const. Adam Morris — were involved in the arrest of a 46-year-old man in February 2013.

"While transporting the man to the police station, there was an interaction between the man and three officers," according to a statement from the SIU.

The man who was arrested was later taken to Humber River Regional Hospital and was found to have been seriously injured, the SIU probe found.

​The three officers will appear in provincial court on Nov. 3.

The SIU began investigating the incident in 2015, although it occurred two years earlier. The arm's length agency, which investigates incidents involving police that result in a civilian injury or death, said in a release that it began looking into what happened as soon as it learned of the incident.
