TORONTO -- A civilian police employee is facing 22 new charges for alleged unauthorized use of the Toronto police database.

Investigators say the 28-year-old temporary clerk with the force's forensic identification service was charged in July with two counts of breach of trust.

It was alleged that Erin Maranan of Thornhill, Ont., made searches of the police database in February 2014 and September 2014 that were not for official police business.

As a result of further investigation, police say Maranan was charged Wednesday with an additional 20 counts of breach of trust, and single counts of perjury and personation.

She was to appear in Toronto court on Wednesday.
