Two men were charged Friday in connection to the stabbing of a security guard who attempted to stop a break-in in the Yonge-Dundas Square parking lot.

Police say the guard was attacked Thursday after confronting a group of three men breaking into cars parked in the underground parking lot adjacent to the Eaton Centre.

Police said the security officer, with the Toronto Parking Authority, was alerted to a possible break-in and went to investigate.

Police say he was approaching a vehicle when one of the men exited the car and stabbed him several times in the back, neck, face and arms.

The guard was rushed to hospital with life-threatening injuries. By Thursday evening his injuries had been downgraded to non-life threatening.

Police arrested one man near the scene, while two others were arrested a short distance away.

Police also recovered the knife used in the stabbing in the College Park mall area.

Jeorge Erny, 21, of no fixed address, has been charged with two counts of mischief, two counts of failure to comply with recognizance and one charge each of aggravated assault, assault with a weapon and possession of property obtained by crime.

Justin Squires, 19, of no fixed address, has been charged with two counts of mischief and two counts of possession of property obtained by crime.

A 17-year-old boy was arrested and released without charges.
