MONTREAL -- The federal government has confirmed that a late Mafia don was given an undeserved cheque for $381,737.

A spokesman for Revenue Minister Kerry-Lynne Findlay says the unwarranted tax refund has since been recovered and has suggested that federal employees responsible could be punished.

The statement comes after a published report that the Canada Revenue Agency gave the since-deceased Nick Rizzuto that refund when, in fact, he owed the taxman $1.5 million.

Rizzuto had just been arrested as part of a sweeping police operation in November 2006 and sent to prison. The elderly Mob boss was eventually released, and was murdered in his kitchen in 2010.

Enquete, an investigative program on Radio-Canada, says Rizzuto received a cheque dated Sept. 13, 2007 for more than $381,000. A photo of a cheque worth $381,737 made out to Rizzuto was posted on Radio-Canada's website on Wednesday.

Radio-Canada, the French-language CBC network, quoted Jean-Pierre Paquette, a former Canada Revenue Agency auditor, as saying he told the Rizzuto family not to cash the cheque and that he even went to Rizzuto's home to get the cheque.

Paquette said he believes the cheque was probably the work of a corrupt civil servant.
