LONGUEUIL, Que. -- Police say they have made a fifth arrest in last year's attack on poker champ Jonathan Duhamel.

Authorities in the Montreal-area community of Longueuil say a 21-year-old man was arrested in western Quebec on Wednesday night.

He is expected to face several charges, including conspiracy, armed robbery and assault.

The four other accused include Bianca Rojas-Latraverse, Duhamel's ex-girlfriend.

Her lawyer said earlier this week she will plead guilty to various charges when she appears in court Friday morning.

Duhamel was attacked last December when people broke into his home, tied him up and stole more than $100,000 in cash from a safe along with some of his most prized possessions.
