Case study:
Two Calgary men alleged to have had sex with underaged girls after meeting them on the internet have been charged in two unrelated cases.
In the first case, Calgary police with help from a special child exploitation unit of officers from different forces, arrested and charged a 24-year-old man with several sex offences.
Max David Miller has been charged with sexual assault, sexual interference with a child under the age of 16, invitation to sexual touching with a child under the age of 16 and luring a child via computer.
In the second case, police arrested a 27-year-old man on Tuesday, alleging that he had sex with a 14-year-old girl who he met online under the internet identity of "9272" or "Keven."
Kevin Andre Thomas has been charged with sexual assault, sexual interference with a child under the age of 16, luring a child via a computer, and invitation to sexual touching with a child under the age of 16.
Thomas had been in contact with the girl in a relationship that spanned several months, said Barber.
In both cases, the victims' parents were monitoring their computers and notified police.
