POLICE have announced a manhunt for a knife-wielding racist who took part in a nazi gang attack on revellers at a London music event on Saturday.

Another man was released from hospital yesterday after receiving superficial injuries in the confrontation at Markfield Park in Tottenham.

Hundreds of people were peacefully enjoying a free event in the north London park as part of global celebrations to mark World Music Day when they were attacked by Polish football hooligans. 

The police confirmed that one unnamed man was rushed to hospital after receiving knife wounds and said local CID officers were trying to identify the gang member who launched the attack. 

Video footage of what the police believe to be a separate attack at the same event involving the members of the Zjednoczeni Emigranci group was published online yesterday. 

Punches, bottles and even a red flare can be seen being thrown as partygoers come together to force back the forty-strong fascist mob in the footage. 

Over 70 members of the group — believed to be a collection of Polish football hooligans in London — confirmed they were set to attend their picnic in the park. 

A police spokesman said: “We’re aware there’s some footage of disorder. I’m not aware of any arrests or injuries as a result that disorder.”

But he added that one gang member was arrested for racially aggravated common assault after swiping a kippah cap from the head of a Jew. 

A witness to the attack wrote on Facebook: “I saw them attack an Orthodox Jew, they were organised and went in large groups to cause trouble.”

Unite Against Fascism national secretary Weyman Bennett described the Polish group as “primarily anti-semitic.”

A meeting of Polish and Jewish leaders in the north London community has been called for tomorrow in order to make a united stand against the group. 

Mr Bennett told the Star: “The local polish community goes all the way back to the 1940s when they fled the nazis. 

“We don’t want the neo-nazis to feel they can build a base in Haringey but we don’t want to feed into the Polish backlash over immigration.

“We need to join together to oppose the fascists wherever they’re from.”
