Ottawa Police are investigating an "incident" during the Ottawa Fury FC game at TD Place.

It happened during the second half of the Canadian Championship semi-final match between the Fury FC and Toronto FC.

In a statement, OSEG says "members of the TFC supporters group smuggled a small quantity of fireworks into the stadium and ignited them." OSEG adds the "fireworks flared and boomed for a short time and were quickly extinguished by TD Place security."

No one was hurt, and OSEG says the perpetrators were ejected from the stadium.

The flare didn’t last long and the game continued after the debris was cleaned from the stands as well as debris that ended up on the field.

How the flame ended up in the stands is still not confirmed. OSEG says all members of the visiting supporters group had been subjected to bag checks and security scans prior to entering the stadium, adding "no fireworks or other devices were detected."

Ottawa Sports and Entertainment Group could face a fine for letting the flare get through security.

OSEG says TFC has "apologized for the behaviour of the members of the supporters group responsible for igniting the fireworks."
