Ottawa police confirmed an OC Transpo driver was assaulted on a bus in Stittsville Wednesday but are not pursuing an investigation after the driver refused to make a statement.

City officials said transit security are also looking into the incident, which happened on the No. 96 bus around 9 a.m. Wednesday.

A union grievance officer with the Amagamated Transit Union Local 279 told CBC News the driver was "sucker-punched in the eye" by a male teenager upon entering the bus.

Mike Fecteau said the teen ran off the bus after the alleged incident and has not been identified.

Fecteau also said the driver, in his 30s, did not want to pursue a police investigation.
