The suspects — all between 16 and 18 years of age — face charges including robbery, armed assault, intimidation and assault causing bodily harm.
The teens were arrested yesterday in Pierrefonds-Roxboro and Ile-Bizard–Sainte-Geneviève.
"They were rowdy with other young people, trying to steal their money or other items. We know also they went to different parties, invited themselves to those parties to start a brawl or stuff like that to intimidate other young people," said Raphael Bergeron with the Montreal police.
Three of the suspects are known to police for past crimes including home invasion and drug dealing.
Two of the seven suspects arrested appeared this morning in youth court, while the other five were released on bail.
Police say these arrests are the result of a two-month investigation.
Police say this investigation was initiated following complaints from young people living in Île-Bizard.
According to a police news release, since mid-September, suspects terrorized young people, approaching victims in public places to steal their money, sometimes beating up their targets or threatening them with a knife.
The suspects allegedly also sent threatening messages to intimidate victims.
In June 2012, Quebec enacted Bill 56 to prevent and combat bullying in schools.
