PORTLAND, Ore. (AP) — A Portland man was sentenced to more than seven years in prison after his conviction for sexually trafficking a girl he started grooming when she was 11 years old, authorities said Friday.

The Oregonian/OregonLive reports Ahad Shaukak Hasan, Jr., pleaded guilty to rape in the second degree and compelling prostitution, prosecutors said.

Investigators said Hasan initiated contact with the victim on social media in 2012 when she was 11. Hasan, then 19, persuaded the girl to meet him in person and began grooming her for sexual exploitation, authorities said.

Hasan raped the girl when she was 12 and began monitoring her social media accounts, according to prosecutors. In 2017, Hasan took the her to a strip club and forced her to have sexual contact with other individuals for money.

The victim was contacted by law enforcement in 2017 after undercover officers with the Clackamas County Sheriff’s Office responded to an online ad for sex, officials said. Hasan was arrested in May 2018. He was previously convicted of unlawful possession and unlawful use of a weapon, according to court documents.
