Chaos ensued on stage at Toronto’s V Festival last night when Oasis singer Noel Gallagher was attacked, and left with a suspected fractured rib and ligament damage, in front of an audience of 40,000.

A man appeared as the band played Morning Glory and ran at the Gallagher, 41, from behind, sending the singer, who had a guitar strapped on, flying into the monitor speakers.

As security sprinted on stage at Toronto Island Park, the man tried to run but fell into a microphone stand as the two guards grabbed at his arms.

He was dragged off stage, but before the security guards could get him into the wings, Gallagher’s brother, Liam, 35, ran at him and threw a punch, which failed to connect.

A security guard tried to restrain the singer by grabbing his shoulders, but he shrugged him off and followed his brother’s attacker off into the wings.

Noel was helped off stage and the rest of the band abandoned their instruments and followed the brothers.

The crowd were left facing an empty stage and yelling for the band to come back.

Eventually Oasis returned to finish their set but afterwards Noel was taken to hospital with suspected fractured rib and ligament damage.

Today, a spokesperson for the band said Noel “fell heavily on to his monitor speakers” and that a decision was yet to be made as to whether Oasis would play their next scheduled concert in Ontario on Tuesday.

The spokesperson said the unidentified attacker had been detained by police who were investigating the incident.

Oasis is back touring to promote their forthcoming release Dig Out Your Soul – the band’s seventh studio album.

All six of their previous albums have reached No. 1 on the UK charts and, 14 years after first finding fame, the group are still considered one of the country’s most successful bands.
