Following a four-month investigation, the Calgary Police Service Sex Crimes Unit has laid additional charges against a local psychiatrist.

On Tuesday, March 23, 2010, a charge of sexual assault was laid against 71-year-old Aubrey Levin following allegations from one of his long-term patients.

Following this charge, the Sex Crimes Unit was approached by numerous people alleging sexual assault by Levin during counseling sessions or court-ordered visits, police said. According to police, these assaults allegedly occurred at Levin’s Peter Lougheed Centre office or examination rooms.

As a result, investigators have identified 20 additional complainants and have charged Levin with 20 counts of sexual assault. This brings to 21 the number of complainants and charges against the accused, according to police.

Levin appears in Calgary Provincial Court today.
