A Swedish prosecutor has requested to detain ASAP Rocky another week in pre-trial detention to allow police to finish investigating a fight which took place in Stockholm last month.

According to reports, Rocky was in solitary confinement before the White House intervened and demanded that he be given better prison conditions after Kim Kardashian and her husband Kanye West lobbied on his behalf.

"Thank you @realDonaldTrump, @SecPompeo, Jared Kushner & everyone involved with the efforts to Free ASAP Rocky & his two friends. Your commitment to justice reform is so appreciated," Kim tweeted on Thursday.

"Jared immediately got Rocky moved to better living conditions," Pastor Darrell Scott of the URC told Page Six. "They had this guy in a crap hole. I don't know if it's a different facility [that he's now in], but he's at least on a different floor. It's better surroundings."

"[Trump] asked, 'Do you like the guy, do you trust him?' And he said, 'OK, we'll look into it then.' " Scott added, "It was never a publicity grab . . . It's just this administration trying to help an American citizen overseas who's in dire straits."

According to prosecutor Daniel Suneson, police "have worked intensively" with the preliminary investigation.
