Gatineau police arrested a 21-year-old man near his home yesterday after a warrant was issued for his arrest by police in Boucherville, the Montreal-area suburb where Duhamel lived.
He is the fifth person to be arrested in connection with the bizarre case, which left Duhamel beaten and robbed of $115,000 cash and jewelry worth $50,000.
Bianca Rojas-Latraverse, Duhamel's ex-girlfriend, was among those arrested and charged with armed robbery, breaking and entering, forcible confinement, assault and conspiracy.
Earlier this week, Rojas-Latraverse's lawyer said her client intends to plead guilty to some of the charges.
John-Stephen Clark-Lemay, 22, and Anthony Bourque, 20, were also charged in connection with the robbery and assault.
Another person, André Robert-Perron, 27, was charged with possessing stolen property. Police alleged he was found with the poker champion's stolen Rolex watch.
Const. Mark David of the Longueuil police wouldn't say if a deal reached with any of the accused led to the identification of the latest suspect in the case.
"With our investigative techniques, we found out who that [other] person was," he said.
"The minute we had enough evidence, we received a warrant and the Gatineau police assisted us in this case."
Beaten and robbed
Duhamel won a world title in 2010 in Las Vegas, earning $8.9 million US.
The poker star told police he was sleeping on Dec. 21, 2011, when a man rang his doorbell at his Boucherville, Que., claiming to have a package to deliver.
When Duhamel opened the door the man forced his way in, and a second person appeared at the entrance.
Duhamel said his attackers threatened him, beat him and demanded to know where he kept his safe.
After he opened his safe, he was tied up and robbed.
The attack left Duhamel in hospital with minor injuries.
The fifth suspect was transported from Gatineau to Longueuil police headquarters and is undergoing questioning, David said.
He is expected to be arraigned today on eight charges including robbery, forcible confinement, uttering threats, mischief and breaking and entering.
Rojas-Latraverse is scheduled to return to court tomorrow.
