The 31-year-old is accused of sexually assaulting a 12-year-old boy. The alleged crime took place last year when he contacted the victim on the boy's MySpace page.
"He has talked about other relationships he has conducted on the internet and we are trying to explore those to see if any more of them involved children," said Tom Dart, Cook County Sheriff.
Police say online chats between the two led to phone calls and that they agreed to meet. Khan reportedly picked the boy up at his house, brought the boy to Khan's home where he sexually assaulted him, and returned the boy to his house.
Police say the boy later shut down his MySpace page, but was contacted a year later by Khan, who found the boy in a different chat room. Khan was arrested Monday night in a sting set up by the sheriff department's child exploitation unit.
"Parents need to wake up and they need to stop living in some delusional world that their child is safe in their house on the computer. The computer can be quite often, like in this situation, very, very dangerous," said Dart.
Khan is charged with predatory criminal sexual assault of a child. He faces up to 30 years in prison if convicted of the Class X felony.
