A 26-year-old man charged after a Boxing Day shooting at the Tanger Outlets mall in Ottawa remains in custody after he made a brief court appearance on New Year's Eve.

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, and one of them was Ali, police confirmed. Both men had been released without charges but they remained persons of interest in the case.

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 arrested Ali in a car in Vanier on Tuesday evening and executed a warrant in an east-end home related to the arrest. Ali is known to police, according to Acting Ottawa Police Chief Jill Skinner.

In February, he was convicted of unlawful entry and possession of a controlled substance after a home takeover on Baycrest Drive. Ali was sentenced to 22 days in jail for the conviction and handed a $400 fine.

He appeared in court for a brief time on Wednesday and he was scheduled to return to court on Jan. 7. Ali remains in custody.

Guns and gangs unit grows after recent violence

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.

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.
