A Windsor man has been arrested following a sexual assault investigation in LaSalle.
The investigation was launched this month after a family in the town contacted LaSalle police.
Investigators say a suspect was identified and later arrested.
Arnold Dorion, 74, is charged with two counts of sexual assault and two counts of sexual interference.
The victim, who cannot be identified, is a child under the age of 18-years-old and police say the accused had been in a position of trust at the time of the alleged incident.
Investigators say the accused is a self-employed, private educational tutor who advertised their services by way of local classified, buy and sell websites and by word of mouth.
The case remains under investigation.
