Four years after they were charged, three TTC employees were found guilty on Friday of obstructing justice and fabricating evidence.

Michael Schmidt, Tony Catic and Jan Posthumus were among the five transit enforcement officers originally charged in 2013. The TTC’s executive director of communications Brad Ross confirmed that they were found guilty.

Two other officers, James Greenbank and Neil Malik, were acquitted of all charges, Ross said.

The case began in early 2013 when the TTC fired eight of its then 40 transit enforcement officers.

The five men were charged in connection with an alleged fake fines scheme, which it was alleged, was designed to make it look as though they were working when they weren’t, the Toronto Star reported at the time.

According to Ross, the arrests were made after a joint investigation by the TTC and Toronto Police, which included the surveillance of some enforcement officers.

The Star reported in 2013 that many of the fabricated tickets were for loitering and solicitation, which carried a $195 fine.

Several hundred tickets were issued to homeless people, although the TTC does not usually ticket homeless people for loitering or panhandling on its property.
