Lil Wayne’s afterparty in Montreal, Canada, last night (Aug. 18) was just shut down after pepper spray came out the air ducts, forcing everyone in attendance to be evacuated.

Accoding to TMZ, Wayne was hosting an event at a club called La Mouche to cap off his tour stop there when an intruder snuck into the back room and unleashed the chemical into the ventilation system.

So far, it’s unclear if police are investigating, but a rep for Lil Wayne told the entertainment site that the rapper is “okay and gearing for his next stop in Toronto."
