JANE’S ADDICTION has apologized to fans for the onstage altercation in Boston that abruptly ended the band’s concert.

The September 13 show at Leader Bank Pavilion came to a sudden end after singer Perry Farrell bumped Dave Navarro‘s shoulder with his own before seemingly yelling at the guitarist. Navarro then placed a hand between himself and Perry before Farrell appeared to throw a punch at him. Another man then jumped between them, breaking up the fight.

Earlier today (Saturday, September 14),JANE’S ADDICTION offered a “heartfelt apology” and said it is canceling its next concert, in Bridgeport, Connecticut, but gave no further details about the remainder of the tour, which is scheduled to continue through October 16.

“We want to extend a heartfelt apology to our fans for the events that unfolded last night,” the band wrote in its Instagram story. “As a result we will be cancelling tomorrow night’s show in Bridgeport. Refunds will be issued at your point of purchase – or if you purchased via a third-party reseller (StubHub, SeatGeek, etc),reach out to them directly. Thank you, JANE’S ADDICTION“.
