Ross Landry says officers acted quickly in the matter, though he added that he was saddened to hear of the allegations.
The boy was charged with possessing, making and distributing child pornography after he allegedly posted a video online last month of himself having sex with a 15-year-old girl.
He is due in Halifax provincial youth court on June 20.
Landry also says he expects there will be an increase in such charges once a new cyberbullying investigative unit is in place.
He says his goal is to have the unit running this fall.
