Rockers Antemasque have come under fire after video footage appeared to show a bandmember allegedly hurling a kettle full of water into the crowd at a festival in New Zealand.

The band, which features former Mars Volta stars Omar Rodriguez-Lopez and Cedric Bixler-Zavala, was among the acts playing at the Westfest event at the Mount Smart Stadium in Auckland on Tuesday (03Mar15), but the gig was marred by reports several audience members were hurt.

Video footage which has emerged online appears to show frontman Bixler-Zavala throwing a plastic kettle into the crowd, and gig-goer Hugh Smith has told the New Zealand Herald he and his friends were hit with hot water.

Smith alleges his friend suffered a nasty burn on his arm, and shared a picture of the injury. In an email to the publication, he writes, "I threw my hand up to catch it (the kettle) before it collided with my friend's face... This bruised my hand and then splashed hot water all over him and my face. It b**ody hurt. My friend's arm went all burny pink."

Another attendee tells the newspaper, "Something whizzed over my shoulder and into the crowd behind me. I didn't see what the object was but other punters and I were splashed with hot water, or hot coffee, as it flew by... It wasn't scalding hot, but it was hot. I didn't get the lion's share of the splash, I got it on my face and down my right arm."

Antemasque have yet to respond to the allegations. The band was previously linked to Red Hot Chili Peppers star Flea, who played bass on some of their tracks.
