Police raid home of Montreal ex-director general Robert Abdallah

Police are raiding the home of Robert Abdallah, Montreal's former director general, Radio-Canada reports. 

Quebec provincial police cars were spotted outside a Pierrefonds home on Wednesday morning, which Radio-Canada reports is the home of Abdallah​.

The anti-corruption unit (UPAC) has confirmed there are currently 90 police officers carrying out raids in the province, although officials would not confirm where those searches are being carried out.

Abdallah was Montreal's director general from 2003 to 2006.

The former top bureaucrat has been accused of accepting money in a city contract kick-back scheme.

Former construction boss Lino Zambito testified at the Charbonneau commission in 2012 that Abdallah, when he was the top civil servant in the city, instructed him through a middleman to use piping from a particular firm while working on a major sewer contract.

The piping was $300,000 more expensive — but Zambito said he was assured by a city engineer acting as a middleman that he would be compensated and informed that that amount would go to Abdallah as part of the deal.

Members of the board of the Port of Montreal have said that they were pushed to appoint Abdallah by Harper's former communications director, Dimitri Soudas. Abdallah was not appointed in the end, and after leaving city hall, he went on to work in the construction industry.

The allegations against Adballah at the Charbonneau commission have not been proven in court and he has denied them in media interviews.
