A shirtless passenger allegedly sparked a brawl on board a flight after urinating on a passenger.

According to the Daily Mail the Air Mediterranee flight was travelling from the Algerian capital of Algiers to Paris when the drama unfolded, forcing the plane to divert to Lyon.

Passengers claim a shirtless man was allegedly responsible for the bizarre incident and was overpowered by the crew.

Halfway through the 90 minute flight one of the 166 passengers reportedly became aggravated because he wasn't allowed to smoke or drink, French media have reported.

The man was met by police at Lyon's international airport and escorted off the plane.
