MONTREAL -- The former CEO of engineering and construction giant SNC-Lavalin is expected to appear in court at a yet-to-be-determined date to face fraud charges.

Pierre Duhaime was released from custody last night, several hours after he was taken from his home by police investigating alleged fraud involving a Montreal hospital.

The arrest warrant alleges that Duhaime and Riadh Ben Aissa, another former top executive, also committed conspiracy to commit fraud and uttered false documents in connection with a contract pertaining to the multibillion-dollar McGill University Health Centre.

The company said earlier this year that it informed police about the results of an internal investigation into 56 million dollars worth of payments that resulted in the resignation of its CEO.

Duhaime received a $5-million payout after he stepped down last March.

His arrest is the latest blow to the 101-year-old SNC-Lavalin, which is embroiled in a number of corruption scandals in several countries.
