Police laid 11 charges against Yaqoub Ali, most related to the possession and use of a firearm, after one person was injured in the Dec. 26 shooting at the newly-opened outlet mall in Ottawa’s west-end community of Kanata.
Two men in their late 20s had been arrested after the shooting near the Adidas and Polo Ralph Lauren stores. Both were released without being charged but they remained persons of interest in the case.
Police also said the victim, a man in his late 20s who was shot once in the foot, has been "uncooperative" with investigators. All those involved are believed to be part of the Crips gang.
Investigators from the Ottawa police guns and gangs unit laid 11 charges including careless use of a firearm, pointing a firearm, possession of a dangerous weapon, carrying a concealed weapon and possession of a restricted firearm without a licence.
Police officers also executed a warrant in an east-end home related to the arrest on Tuesday evening. Ali is known to police, according to Acting Ottawa Police Chief Jill Skinner.
Gang-related violence sparked over holidays
Earlier this week, police said they believed the shooting was "infighting" among members of the same gang. They reviewed surveillance video and said they were searching for two more suspects.
In 2014 there have been 48 shootings in Ottawa and this case means 11 have led to an arrest.
Also on Monday, there were two more gang-related shootings in Ottawa that left two men injured.
That increase in gang-related violence has led to a boost in the size of the guns and gangs unit, according to Skinner.
"We've doubled the number of gang investigators that we have and they're going to continue to work on this. We've increased the number of front-line uniformed members out there doing the targeting so we get that intelligence information back and we're able to put cases together," she said.
