Quebec’s anti-corruption squad conducted another raid Tuesday in connection with the city's cancelled water meter contract.

Police from the UPAC squad searched the offices of Morrow Communications, a firm owned by Gerald Tremblay's former campaign manager André Morrow.          

The company also did work for GENIeau, the private consortium that was awarded the water meter contract, worth $355-million. Cancelled in 2009, it was the largest awarded by the city at the time.

Last week, UPAC conducted raids at the homes of former Lachine mayor Claude Dauphin, and Sammy Forcillo, a former member of Montreal's executive committee.

Tuesday marked the seventh day of raids linked to the water meter investigation in the past six weeks.
