The 23-year-old has been charged with sleeping with underage in the country which breached the law in Sweden.
The player on several occasion has been allegedly been involved in the scandalous act since joining Allsvenskan giants Malmo FF.
Sarfo who is been accused of the offense has on countless times denied the charges levelled against him.
"I mean he has had sexual intercourse with the plaintiff, and I claim it's like judging rape against children," said prosecutor Rikard Darell.
"We're lucky, Sarfo has not managed to get Swedish citizenship," claims American-born lawyer, Blake Pettersson.
"The man has previously acknowledged sexual intercourse with the plaintiff, but has claimed that he did not know she was under 15 years old."
"Date of judgment will be announced later this afternoon, but Mr. Sarfo may stay in the detention so we can assume he is sentenced."
Earlier this month, a heartbreaking picture of talented Ghanaian emerged with the enforcer in handcuffs and shackles like a terrorist as he arrived in a Swedish court from prison for the start of his rape trial.
Coach Kwesi Appiah handed the player his maiden Black Stars call-up when he was invited for Ghana’s FIFA World Cup qualifier against Uganda last year but the allegations surrounding him has also halted his invitation to the Black Stars team.
