A Monopoly game escalated into a fight with a samurai sword that left 2 men in the hospital

• Monopoly players in Belgium got into a fight with a neighbor who was angry about the noise levels.
• The neighbor's son brought out a Japanese katana sword and began fighting with a player.

A Monopoly game ended in violence after a man brought out a Japanese katana sword, leaving two men in hospital with serious injuries, one of which was life-threatening, according to reports.

A group of four people was playing the classic board game on April 2 on a sidewalk in Forest, Belgium, when a neighbor came out of his house wielding a stick in his hand, the Belgian newspaper La Libre reported.

Midi Libre, a French newspaper, noted that the group may have been homeless.

La Libre reported that those playing the game and the frustrated neighbor got into a verbal altercation, which prompted the neighbor's son to join the fracas.

According to Mail Online, it was 5 a.m. and the neighbor was annoyed by how loud the group was being.

The son came out of his home carrying a katana sword — a Japanese sword with a single-edged, curved blade and long grip that was once used by samurai in feudal Japan.

He then got into a physical fight with one of the Monopoly players, according to Mail Online.

"The player tried to grab the katana and removed the holster," police said, per La Libre. 'The son tried to get it back."

The sword's sheath was damaged in the scuffle, exposing the blade, which sliced them both, Mail Online reported.

Both men were hospitalized with serious injuries, with the Monopoly player being released the next day and the sword owner sustaining a deep artery cut.

The man was initially in a life-threatening condition, according to the Belgian newspaper Le Soir, but his current state is not known.

Zone de Police Midi, the police force which oversees Forest and the surrounding areas, did not immediately respond to Insider's request for comment.

The names of those involved have not publicly been released.
