A blind, former paralympian convicted of sexually assaulting a woman won't spend any time in jail.

The reason for Judge Heather Lamoureux's decision in a Calgary courtroom Tuesday was largely based on the grounds that Alberta's correctional institutions cannot accommodate Keith Myette's disability.

Instead, Myette — who requires 24-hour assistance from his guide dog — will serve his 18-month sentence under house arrest.

The Crown had been asking for 18 months to two years behind bars.

Defence lawyer Brendan Miller says putting a blind criminal in jail would be a human rights issue.
