A pair of teenagers have been arrested in relation to a robbery involving a firearm.

Stratford Police say two people were confronted by two males near the Avon River Friday night.

One of the teens reportedly pulled a black handgun from his front waistband and pressed it against the chest of one of the victims.

The accused males spit on the victims and demanded they empty their pockets. A cell phone and wallet were handed over.

Police were called to the scene and located two males fleeing the area.

A 17-year-old male from Toronto and 15-year-old male from Stratford were taken into custody and charged with multiple criminal offences.

It was determined that the accused teenagers and victims did not know each other.

OPP Underwater Search Team arrived to the Avon River on Monday took look for the firearm they believe was thrown into the water.
