Toronto police say three more complainants have come forward to allege they were sexually abused at the hands of a bus driver who drove routes in Scarborough.

Frank Gavas, 61, was charged last month with six offences relating to the alleged sexual assault of three pre-teens between September 2015 and Jan. 15, 2016.

After making the allegations public, police say three more victims, two pre-teen girls and one pre-teen boy, have come forward alleging they were also abused.

As a result, police have laid six new charges against Gavas — three counts of sexual assault and three counts of sexual interference.

He is expected to appear in court at Old City Hall on Feb. 25 at 10 a.m.

Investigators believe there may be other victims who have not yet come forward.

Gavas worked for Stock Transportation since 2006 and has driven for a number of schools in the Scarborough area, including Georges Vanier Secondary School, Wexford Public School, George Peck Public School and Sloane Public School.

Anyone with information is asked to contact police at 416-808-4100, or Crime Stoppers at 416-222-8477 (TIPS).
