A Toronto teacher faces additional charges two months after police arrested him in connection with an alleged sexual assault of a high school student.

Brian Ross, 36, was charged on Monday with sexual assault and sexual exploitation after a 16-year-old student at Marshall McLuhan Catholic Secondary School alleged she was assaulted between September 2011 and June 2012, police said.

Ross was previously charged with sexual assault and interference in March after he drove home a 15-year-old girl in March 2017 to discuss school-related issues but allegedly sexually assaulted her.

Ross taught at two different schools with the Toronto Catholic District School Board over the past decade and was also involved in coaching athletics, police said in a news release Thursday.

He has most recently taught at Senator O’Connor College School on Rowena Dr. from Sept. 1, 2016 to Feb. 18, 2019, police said. He had previously worked at Marshall McLuhan high school on Avenue Rd. from Sept. 1, 2006 to Aug. 31, 2016, police said.

He is scheduled to appear in court May 24.
