LAVAL, Que. -- Police were conducting their latest anti-corruption raids in Quebec on Wednesday and various media reports said they were targeting the mayor of Laval once again.

A spokeswoman for the provincial anti-corruption unit said raids had been carried out at different financial institutions.

But she wouldn't discuss reports that the targets were safety-deposit boxes linked to Gilles Vaillancourt, the powerful Montreal-area suburban mayor.

Police have already raided two of Vaillancourt's residences and his offices at city hall.

The mayor has run Laval, Quebec's third-largest city, for more than two decades with very little political opposition.

He has been hit with allegations of bribery in recent years -- but he has angrily denied them.

A spokeswoman for Vaillancourt said she couldn't confirm whether the raids were linked to the mayor; she said she learned about the police operation from a television news report.
