Vancouver police have recommended 83 criminal charges against 25 more people who allegedly participated in the Stanley Cup riots in June 2011, including two suspects in the attack on a Good Samaritan.

The recommended charges are part of the ongoing investigation of the destructive riots that broke out after the Vancouver Canucks lost the Stanley Cup to the Boston Bruins in game seven.

Charges are recommended against a 16-year-old Surrey boy and a 20-year-old Richmond man, both of whom are alleged to have been among the group of 15 rioters who swarmed Good Samaritan Robert MacKay as he tried to stop rioters from smashing the windows of a department store.

Police announced Friday that in the past few weeks, four more rioters have pleaded guilty to the charges they faced.

Alex Peepre, 20, of Windermere, B.C., pleaded guilty to participating in a riot and assault; Robert Snelgrove, 24, of Vancouver, pleaded guilty to participating in a riot and break and enter; Richard Dorosh, 22, of Burnaby, pleaded guilty to participating in a riot; and Sean Yates, 22, of Burnaby, pleaded guilty to participating in a riot and assaulting a police officer.

The four guilty pleas bring the total number of guilty pleas in the riot to seven.

Riot investigators have so far recommended 592 charges against 200 rioters.
