A man has been charged in connection to a prison break from the Bowden Institution in southern Alberta in 2015 while he was an employee there.

Innisfail RCMP say Sylvain Martin escaped from the minimum security annex at the Bowden Institution, about 110 kilometres north of Calgary, on April 16, 2015. He was arrested later that year on a Canada-wide warrant in Quebec and returned to the custody of Corrections Canada.

In a release, police say their 19-month-long investigation into Martin's escape revealed that a Bowden Institution employee "developed an inappropriate financial relationship" with Martin while the man was incarcerated there.

Martin was serving a 10-year sentence for fraud, obstruction of police, forgery and other offences at the time of his escape.

Peter Edgar, 61 of Red Deer County, is charged with two counts of permitting or assisting escape. He is scheduled to appear in a Red Deer court on Oct. 25.

Edgar is no longer employed by Corrections Canada.
