Kingston's police chief has come to the defence of his son after the University of Ottawa student resigned from a student leadership position when a private Facebook chat involving sexually threatening banter was made public.

Alexandre Larochelle resigned from his position as the vice-president social for the criminology student association after the student union president, Anne-Marie- Roy, published a Facebook conversation in which he and three other students engaged in sexually threatening banter about her.

At one point in the Facebook conversation, Larochelle wrote, in reference to Roy, "Someone punish her with their shaft."

In a joint statement, Kingston Police Chief (and former Ottawa police deputy chief) Gilles Larochelle and his wife Tessa said they stand with their son and said "his words do not reflect his true character or values."

"He knows how wrong it was to make the comments and to participate in such a conversation. Response to his words has been wide spread and social comments have vilified him," they wrote in a statement released Tuesday.

"Alexandre made a mistake that he has apologized for and resigned from a position he was very committed to. He regrets the hurt he has caused. We ask you to give him the chance to learn and make amends."

The family said they would not comment any further.

Alexandre Larochelle said in an email to CBC News on Sunday he had apologized twice, the first time on Feb. 10, when Roy first obtained screenshots of the conversation and confronted the men.

He and the three other men, Michel Fournier-SimardAlexandre Giroux and Robert-Marc Tremblay, also threatened to sue Roy for releasing the Facebook chat, but later apologized and resigned from their respective positions. Larochelle also said he would not be pursuing legal action.
