A$AP ROCKY NOW IN CUSTODY FOR 2 WEEKS

A judge just decided that authorities could detain A$AP Rocky for 2 weeks while prosecutors investigate further to determine if they want to charge him with aggravated assault. The stakes here are enormous -- if convicted he could be sentenced to 6 years in prison.

Swedish prosecutors are asking a judge to allow them to hold A$AP Rocky and members of his crew for 2 weeks, while they investigate the alleged assault Tuesday for which he was arrested. Swedish authorities are normally allowed to keep people for only 3 days, so they clearly have an agenda

What might help A$AP's case is that another video surfaced, showing the alleged victim harassing A$AP and hitting his bodyguard with a set of headphones. The guy was harassing A$AP and his crew for about a half hour before they had enough.

A$AP actually tried to be a peacemaker ... telling the guy, "We don't wanna fight y'all. We don't wanna go to jail."

Swedish prosecutors say they are releasing the bodyguard now due to "insufficient evidence" but they are not releasing A$AP. That suggests the second video still doesn't clear the rapper, and they still view this as an assault.
