MONTREAL -- Mark Lafleur is once again in trouble with the law.
Police in Blainville, Que., a suburb just north of Montreal, arrested the son of hockey legend Guy Lafleur on Wednesday night.
He was later released on a promise to appear next December.
Police say he faces an assault charge related to an alleged domestic violence incident as well as a drug possession charge.
In February 2009, Mark Lafleur was handed a 15-month conditional sentence on charges including sexual assault, battery, unlawful confinement and uttering death threats against his ex-girlfriend.
Guy Lafleur just ended his own three-year legal battle stemming from his sonıs trial.
He was acquitted in August of the charge of giving contradictory testimony during Mark Lafleurıs 2007 bail hearing.
The acquittal overturned the decision of Judge Claude Parent, who had originally found Guy Lafleur guilty in 2009.
