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 son¹s trial.
He was acquitted in August of the charge of giving contradictory testimony during Mark Lafleur¹s 2007 bail hearing.
The acquittal overturned the decision of Judge Claude Parent, who had originally found Guy Lafleur guilty in 2009.
