TORONTO - Police say four people, including two Ontario DriveTest employees, have been charged with fraud-related offences after driver's licences were allegedly issued under fake names.

Toronto police say they uncovered more than 164 fake identities that were used to obtain credit and other provincial and federal identification during a three-month investigation.

Police say another 140 identities have been deemed suspicious.

It's alleged that some of the IDs were used to bypass government regulations such as the Family Responsibility Act, while others were used to skirt court orders stemming from impaired driving charges.

Police say the IDs had a street value of about $5,000 each.

More than a dozen charges, including fraud, forgery and conspiracy, were laid against the four, who are residents of Toronto, Brampton and Orangeville.

DriveTest's 550 employees have been on strike since Aug. 23, with job security being the key issue.
