Quebec anti-corruption unit raids Roche engineering firm

About 50 investigators from the provinces anti-corruption unit (UPAC) raided the Quebec City headquarters of engineering consulting firm Roche early Wednesday morning.

The investigators began searching through Roches documents at approximately 6:30 a.m. ET.

UPACspokeswomanAnne-FrdrickLaurence said no arrests are expected for now, but investigators will be questioning some employees.

"The elements of this search, as well as the motives of the investigation, are of a confidential nature," Laurence said.

Similar searches under Operation Hammer took place at Roches Montreal and Quebec City offices in 2010. At the time, officers were looking for proof of allegations of fraud and breach of trust in the construction industry.

Operation Hammer wasformed in 2009 to investigate corruption in the construction industry.UPACwas created two years later, in early 2011.

Roche has been mentioned at theCharbonneauCommission, the provinces inquiry into corruption in the construction industry. In 2012, a former Roche employee alleged that some of his former co-workershad engaged in bribery in bid-rigging.
