(CNN) A group of celebs have joined a growing cry for rapper A$AP Rocky to be released from a Swedish prison.

He was recently detained in Stockholm after being accused of serious assault, according to CNN Swedish affiliate Expressen.

A Change.org petition seeking his release had more than 330,000 signatures as of Wednesday morning.

"On Sunday, June 30th, A$AP Rocky, his bodyguard and two performers from his show acted in self-defense after two men followed, harassed and physically assaulted them in Stockholm," the petition reads. "Video footage shows the assailants following Rocky and his colleagues, even cutting off where they are trying to walk sometimes, while Rocky pleads to them that he does not want any issues."

Several high profile celebrities including musical artists Post Malone and Shawn Mendes and actress Jada Pinkett Smith have thrown their support behind the petition using the hashtag "JusticeForRocky."
