A linesman named Lennert Bohmer, was arrested after he charged on to the pitch and floored the shot-stopper with a punch from behind.

It was a shocking moment as 34-year-old brutally knocked out the goalkeeper, resulting into a huge brawl which erupted during a match.

He was left unconscious on the ground as his team-mates rushed to his side and desperately called for help.

Paramedics treated the goalkeeper at the scene before he was rushed to hospital in an ambulance.

Chaos erupted after a player was shoved to ground during the match between Hoofddorp club VV UNO and S.V. Geel-Wit in Holland.

Players got stamped on, punches were thrown and one player floored an opponent with a flying kick.

The linesman, who previously played for Geel-Wit, raced onto the pitch with his flag in his hand.

But he dropped the flag and charged towards the goalkeeper – who had just got back to his feet after a scuffle.

Bohmer, who was reportedly the chairman of the Geel-Wit youth committee, landed a huge right hook before players from both teams intervened.

It is understood that the incident is still being investigated by police before it is handed over to the public prosecutor.

A police statement read: “The suspect delivered a punch to a player which caused him to lose consciousness.

“The victim was taken to the hospital as a precaution, and there it appeared he was suffering from a concussion.”

The Geel-Wit board added: “The board of Geel-Wit and UNO will soon meet to discuss this unworthy incident and to restore the relationship between the players and the clubs.”
