In the message, sent on 31 July, he demanded an immediate humanitarian release of Mayers and his two staffers from Swedish jail, as well as their "supervised detention in a local Stockholm hotel pending final disposition". The rapper told the court that he had acted in self-defense after his bodyguard was attacked.
The 30-year-old rapper has been in Swedish custody since July 3, alongside his entourage, in connection with a fight in central Stockholm on June 30. "We didn't know what to expect with these strangers - I'm not from Sweden, so it was really scary", the rapper said.
US President Donald Trump had previously attempted to use his leverage to free the troubled rapper.
One supporter, Emina Moreira, 19, said Rocky has been treated unfairly by the Swedish court system and blamed racism as a possible cause.
Both women who testified Friday maintained their previous statements to police that they saw Mayers and his partners beating and kicking Jafari. Besides A$AP Rocky's bodyguard, the other witnesses questioned Saturday included a friend of Jafari's who was with him the day of the alleged assault.
The Swedish prosecutor, however, rebuffed his plea and noted that it is only up to the court to decide whether somebody can be released from jail.
Following the decision, O'Brien said Friday was "a good day for the United States of America and a good day for the Kingdom of Sweden".
In his testimony, Jafari said he was also hit on the head with a bottle after he followed Mayers' group. I will be calling the very talented prime minister of Sweden to see what we can do about helping A$AP Rocky.
