A Montreal borough city manager committed suicide over the weekend after being questioned at length by Quebec’s anti-corruption unit.

Robert Rousseau spent most of Friday at the headquarters of the Surete du Quebec, meeting with investigators.

The director of divisions and permits for the Montreal borough of Côte-des-Neiges-Notre-Dame-de-Grâce was then found dead at his home in Châteauguay Saturday, Le Devoir reports.

Radio-Canada

reports Rousseau was being questioned about the Upper-Lachine-Wilson condominium project, which is being developed by Tony Magi, who is linked to the Montreal Mafia.

The borough issued a short statement confirmed a death, but did not name the employee.

“Our thoughts are with the family and colleagues who have been struck by a terrible shock today,” the borough said.

Dozens of police officers raided Montreal’s city hall in February, amid allegations of fraud and breach of trust.

“It’s embarrassing as a Montrealer, as a Montreal politician, even as a Quebecer,” said Richard Bergeron, leader of the opposition party Projet Montréal.

Rousseau is survived by a wife and two children, CTV reports.
