Police are stepping up their demand for help in locating a man suspected of committing multiple acts of fraud.

Police say Nelson Plourde, 37, has defrauded 30 people in the past six months, on top of the many people he swindled before they first alerted the public to his scams.

According to police, Plourde approaches people and says he can help them earn money because of a flaw in the ATM system.

Instead he cons his victims out of their bank cards and PIN, and when promising to make a deposit, withdraws as much money as he can from their account.

Plourde often preys on women in their twenties.

Police first warned the public about Plourde in July 2015, but say he is still committing criminal acts and they have had no success in tracking him down.

They know he has been active in several boroughs including the Plateau-Mont Royal, Mercier-Hochelaga, Ville-Marie and Southwest.

Plourde is 1.75 m and 77 kg (5'9", 170 lbs) with short dark hair and white skin.

Anyone who sees him is asked to call 9-1-1 or Info-Crime at 514-393-1133.
