TORONTO - Three of four Toronto police officers charged last month with obstruction of justice and perjury after allegedly providing false testimony in court are facing additional charges.

On Jan. 28, a total of 17 charges were laid against the four officers, and they were suspended with pay as the case goes through the courts.

Court documents show those charges stem from the case of a man accused of drug possession and drug trafficking following a traffic stop on Jan. 13, 2014.

Police say additional charges have arisen from the same set of circumstances as the initial charges, and on Monday Const. Jeffrey Tout was charged with perjury and two counts of obstructing justice.

One count each of obstructing justice were laid against Const. Benjamin Elliot and Det. Const. Fraser Douglas.

Tout, Elliot, Douglas and Const. Michael Taylor are scheduled to appear in court on March 11.
