Police say a Toronto teen is the latest person to be charged in connection with one of the worst mass shootings in the city's history.

Toronto police said Friday that a 17-year-old boy has been charged with two counts of second-degree murder, 22 counts of aggravated assault, one count each of attempted murder and recklessly discharging a firearm.

The teen suspect, who cannot be identified under the Youth Criminal Justice Act, was scheduled to appear in court Friday.

Numerous gun shots were fired during a July 16 barbecue for young people, killing 14-year-old Shyanne Charles and 23-year-old Joshua Yasay. Twenty-three others were sent to the hospital.

Nineteen-year-old Nahom Tseigazab was charged earlier this week with two counts of second-degree murder, attempted murder and 23 counts of aggravated assault.
