Three Toronto police officers have been charged with assault after a man sustained three broken ribs during an arrest.

On Friday the province’s Special Investigations Unit (SIU) said it had reasonable grounds to believe that the officers committed a criminal offence when they arrested 26-year-old Stalin Kiprotich in June.

According to the SIU, at approximately 8:30 p.m. on Monday, June 4, 2012, Kiprotich was arrested near Kipling Avenue and Finch Avenue West, during which time there was an altercation.

Kiprotich was jailed, but after complaining of a sore chest he was taken to a hospital and diagnosed with the fractured ribs.

Toronto police Det. Const. Jason Davis, Det. Const. Keith Osborne and Det. Brian Kay are each facing one charge of assault causing bodily harm.

The officers are scheduled to appear in court on Oct. 9.

The SIU is typically called in to investigate any serious incidents involving police. This includes events where there has been death, serious injury, or sexual assault allegations.

An SIU investigation could determine whether charges should be laid.
