At least one gunshot was fired in broad daylight outside the library at South Fletcher’s Sportsplex Monday, afternoon, Dec. 17, shaking patrons and closing the library for the evening.

“Dramatic afternoon,” witness Zainab Walji wrote on social media. “Don’t want to ever hear a gunshot up close #loud #scary #library.”

No one was injured, Peel police confirmed.

Police said they were called to the area, at Ray Lawson Boulevard at McLaughlin Road, around 2:45 p.m. for an "altercation."

"During that altercation, there were shots fired," said Peel police spokesperson Const. Heather Cannon.

It isn't clear if the incident happened inside the building or outside.

Cannon said the incident is under investigation and no other information is available, including whether arrests have been made.

“It’s an ongoing investigation,” said Cannon. “We’re working on releasing further details.”

Walji wrote on social media that only one shot was fired.

“Was just one shot ... people outside library,” Walji posted on social media. “And then a scuffle. But thankfully no one hurt (apart from maybe one of those guys). Not something you want to see or hear.”
