Jane's Addiction is canceling the remainder of its tour after singer Perry Farrell was seen punching guitarist Dave Navarro at a Boston concert on Friday.

The band announced the decision Monday in a post on social media, noting they "made the difficult decision to take some time away as a group" and they "will be cancelling the remainder of the tour."

"Refunds for the cancelled dates will be issued at your point of purchase – or if you purchased from a third-party resale site like StubHub, SeatGeek, etc, please reach out to them (directly)," the band wrote.

Dave Navarro blames Jane's Addiction tour cancellation on Perry Farrell: 'We hope that he will find the help he needs'

While the statement shared to the band's social media didn't place blame, a more in-depth message posted to Navarro's personal accounts puts the tour cancellation on Farrell.

"Due to a continuing pattern of behavior and the mental health difficulties of our singer Perry Farrell, we have come to the conclusion that we have no choice but to discontinue the current US tour," the statement reads.

"Our concern for his personal health and safety as well as our own has left us no alternative. We hope that he will find the help he needs," the statement continues. "We deeply regret that we are not able to come through for all our fans who have already bought tickets. We can see no solution that would either ensure a safe environment on stage or reliably allow us to deliver a great performance on a nightly basis.

"Our hearts are broken," the statement ends, signed "Dave, Eric and Stephen."

The band previously issued a statement on its Instagram story Saturday, according to CNN and Variety. "We want to extend a heartfelt apology to our fans for the events that unfolded last night," the band wrote, adding that, in light of the scuffle, it had canceled its show in Bridgeport, Connecticut, on Sunday.

On Sunday, Navarro posted a black-and-white Instagram photo of himself with the caption, "Goodnight..."

Dave Navarro, Perry Farrell fight during Jane's Addiction concert in Boston

According to concert footage shared by fans, the band's concert in Boston was halted and came to a dramatic end when Farrell shoved and punched Navarro. Farrell was restrained by crew members and a man who appeared to be bassist Eric Avery as he threw punches and was pulled away from Navarro.

Jane's Addiction was on a reunion tour with their four original members: Farrell, Navarro, Avery and drummer Stephen Perkins. The band is best known for heading the alternative rock wave in the late 1980s and early 1990s. Its hit songs include "Jane Says," "Been Caught Stealing" and "Mountain Song."

Jane's Addiction concert endsafter Perry Farrell punches guitarist Dave Navarro

Navarro exited the band in 2022 due to COVID-19 complications, with Farrell telling the New York Post that he wished he "would have my dear guitar player around" for the band's tour. Navarro returned for this reunion tour, which kicked off in August.

Jane's Addiction has bid farewell and reunited a number of times through the years. The band's original farewell tour launched the very first Lollapalooza in 1991.

Farrell is central to a buzzy Sundance documentary that premiered earlier this year about the Chicago music festival aptly called "Lolla." He is the main voice of the three-episode doc, which is streaming now on Paramount+.

The film details how Lollapalooza helped break bands like Nine Inch Nails (Trent Reznor shares a great story about their first set), Pearl Jam, and Green Day but also became a symbol for selling out.
