TORONTO - Two TTC employees are facing 30 theft-related charges, Toronto Police said Thursday.

Suspicious transactions between the public and TTC workers have been under investigation since the beginning of this year, police said.

In that time, a TTC fare collector took money from TTC patrons but did not turn the money over to the TTC, police allege.

Krishna Rajkumar, 47, of Markham, was arrested on Wednesday and charged with eight counts of theft under $5,000 and eight counts of failing to collect fares.

Police also allege that another fare collector did the same thing beginning in October 2012 up until earlier this month.

Paul Vardy, 56, of Pickering, was arrested and charged with seven counts of theft under and seven counts of failing to collect fares.

The accused are scheduled to appear in court on May 9.

At a town hall meeting with riders on Wednesday, TTC CEO Andy Byford had said he was eager to weed out bad apples.
