Poland's Open'er Festival has replaced A$AP Rocky with Stormzy today after the Testing rapper was arrested in Stockholm after an alleged assault.

The festival thanked Stormzy on socials, writing, "Stormzy is coming to Open’er! This year’s Glastonbury headliner in just a few hours decided to help us, and we are very grateful for that. Respect!"

Pitchfork reports that A$AP Rocky was arrested yesterday (3 July) after reportedly kicking and punching a man on Stockholm's streets.

The "Praise The Lawd" rapper shared footage of the situation on his Instagram, writing, "We don't know these guys and we didn't want trouble, they followed us for four blocks, and they were slapping girls' butts who passed, give me a break."

In a second clip, A$AP Rocky added, "Hits security in the face with headphones then follow us."

CNN reports that A$AP Rocky's lawyer, Henrik Olsson Lilja, said, "We are working hard with this and confident that the prosecutor will take a decision in favor of my client when he gets the full picture."

Stormzy headlines Open'er Festival tonight (4 July). A$AP Rocky is due to play London's Wireless Festival on Sunday (7 July).
