Polish mayor Pawel Adamowicz stabbed on stage during 'Light to Heaven' charity

The mayor of Polish port city Gdansk was stabbed while on stage at a charity event.

Footage which claims to have been shot during the event, shows the incident happened in front of a large, celebrating crowd.

Pawel Adamowicz was rushed to hospital following the attack in a serious condition.

Mr Adamowicz was attacked with a sharp tool during the “Light to Heaven” event, spokeswoman Magdalena Skorupka-Kaczmarek said.

Interior Minister Joachim Brudzinski said Mr Adamowicz called the stabbing “an act of inexplicable barbarity.”

A suspect has been arrested, Mr Brudzinski said.

YouTube video appears to show the moment the terrifying attack took place.

People can be seen waving what look to be sparklers on stage as people in the crowd cheer.

A man then jumps on stage and appears to attack Mr Adamowicz. He remains pacing on stage with his hands in the air, as music continues to play.

It’s understood a knife was used in the incident.

Polish broadcaster TVN claimed that the attacker shouted that he had been imprisoned under the government of Civic Platform, a party to which the mayor formerly belonged.

Mr Adamowicz had no direct involvement in the man’s imprisonment.

Mr Adamowicz posted just hours earlier about his fundraising efforts, boasting on Facebook that he’d raised €5,613.11 ($A8915.30) for the event.

“Thank you sincerely everyone who threw money into my can and helped beat my personal record,” Mr Adamowicz wrote.

Money raised at Light to Heaven was to help purchase medical equipment for children’s hospitals, the Facebook event said.

Some 1200 people indicated they would attend on the event page.

Comments on the video showed support for Mr Adamowicz.

“Adamowicz is a man whose views are far from mine, but I wish him a quick recovery. Such things should not happen,” one wrote.

Mr Adamowicz has been mayor of Gdansk since 1998.

He was part of the democratic opposition born in that city under the leadership of Lech Walesa during the 1980s.

As mayor, he is seen as a progressive voice and has supported LGBT rights and tolerance for minorities.

He showed solidarity with the Jewish community when the city’s synagogue had its windows broken last year, strongly denouncing the vandalism.

President Andrzej Duda said that while he and the mayor have had political differences, “Today I am unconditionally with him and his loved ones, just as – I hope – all of us compatriots are. I pray for his return to health and full strength.”

Gdansk, about 3.5 hours from Poland’s capital Warsaw, is one of the country’s largest cities, with a population about 570,000.
