The conflict unfolded when firemen from Mexico's Heroic Fire Department and Ceda Fire Department were dispatched to deal with the brush fire in the capital Mexico City. But tempers frayed when both sides disagreed over who should deal with the situation and a fight broke out. Scroll down for video . Violence: Police arrived to break up a fight between rival fire brigades in Mexico City - only to end up becoming involved in the brawl . Passer-by Atanasio Rivas Matos, 25, who captured the conflict on his mobile phone, said: 'One of the groups of firemen started spraying the other group with water, who retaliated by throwing bricks at them. 'And then the police arrived.' But rather than calming the situation down, the appearance of the officers seemed to fuel the conflict and the firemen quickly turned on the police. Matos said: 'It was really bizarre. Flash point: Officers were brought in to ease tensions, but had to defend themselves after being attacked by fire fighters . 'The police were trying to separate the two groups when they came under attack from the firemen who started punching them, and then more policemen who turned up to stop the fighting were also attacked. 'It was like something out of a very bad comedy.' Now furious city officials have demanded an explanation. A spokesman for the council said: 'This was appalling behaviour from those we employ to safeguard the city. 'Instead of behaving like public officials they behaved like children in a playground. 'An investigation is underway and we will not stop until we have got to the bottom of what went on.' Meanwhile both fire brigades have blamed each other for the fracas and the attack on police. A police spokesman said: 'We are assisting the city in their investigation.'
