Const. Bruce Shipley and Const. Alfred Wong are charged with public mischief, breach of trust, and fabrication of justice, in addition to the original assault charges.
Transit police spokesperson Anne Drennan said the charges stem from new information related to Shipley's and Wong's actions in February 2012, when they allegedly physically assaulted and pepper-sprayed a 27-year-old man at Granville Station.
Both Shipley and Wong were charge in August 2013 and have been on administrative duties since.
