Many questions about MP Grewal, Trudeau says

OTTAWA — Word of Liberal MP Raj Grewal’s gambling debts surfaced on police wiretaps in a much broader probe into other people suspected of money laundering and terrorist financing, says a source with knowledge of the events.

Grewal’s sudden decision to step down as the member for the southern Ontario riding of Brampton East was prompted by a gambling problem that led him to incur significant personal debts, the Prime Minister’s Office said last week.

The source, who requested anonymity due to the sensitivity of the matter, said Grewal’s debts came to the attention of the Ontario Provincial Police during an investigation of some “particularly shady guys,” who might be involved in laundering drug money destined for an extremist group in the Middle East.
