A former worker at the Alberta Children's Hospital in Calgary has been sentenced to four years behind bars for the inappropriate touching of two girls under the age of 14.

The assaults did not happen at the hospital.

Ronald Arthur Sayers, 56, will also become a registered sex offender for the next 20 years.

Sayers must submit his DNA and is prohibited from owning weapons.

He was found guilty last April of sexual assault and sexual interference in the incidents dating back to 1998.

Sayers appeared composed as the sentence was delivered on one count of sexual interference against each girl.

Victim believed attacks were her fault, court hears

Sayers repeatedly fondled one of the girls from the age of eight until she was 13.

Identified to the court as RMC, the victim believed the attacks were her fault.

She has struggled with depression and was hospitalized after a suicide attempt.

Sayers received three and a half years for those attacks, and was given another six months for fondling an 11-year-old girl.

He was also found not guilty in two other cases involving a 17-year-old and a four-year-old.
