MONTREAL - The son of Montreal Canadiens legend Guy Lafleur is to undergo more psychiatric tests after being charged with sexual assault involving a minor, armed assault, uttering threats and forcible confinement.

Mark Lafleur, 22, appeared in a Montreal courtroom today and is to return to court in about a month.

The alleged assaults against a 17-year-old girl began in the summer of 2005.

Lafleur's lawyer, Jean-Pierre Rancourt, says his client has Tourette's syndrome.
