A Markham man is facing charges for allegedly luring a 15-year-old girl using Internet instant messages and then sexually assaulting her in her home.

Police allege Chou Eng Fong, 27, posed as a teenaged boy using the on-line name M.J.

"He was using MSN Messenger, which is quite a common thing for teens today," Toronto Police Det. Shawna Coxon said Thursday.

According to investigators, Fong arranged to meet the young girl. During their first encounter there was no incident. However, police say Fong allegedly went to her home the next day.

"The following day he attended the girl's home knowing that she would be alone at this time," Coxon said. "And at this time he forced the girl into her bedroom and repeatedly sexually assaulted her for a few hours."

Fong was arrested on Wednesday. He is facing the following charges:

• Luring a child under 16 years of age
• Sexual assault
• Two counts of failing to comply with probation

Following his arrest, police seized two computers and a number of CDs during a search of the suspect's home.

Investigators say other teenagers may have chatted with Fong, allegedly posing as M.J., while using the MSN Messenger service.

Police are asking anyone who may have spoken with him on-line or met him in person to contact the Child Exploitation Section at (416) 808-8500 or Crime Stoppers anonymously at (416) 222-TIPS (8477).

Police urge parents to talk with children about the on-line services they use and the people they communicate with through the Internet.
