Police arrest 47 after huge demo turns violent
Thousands of taxi drivers are up in arms about the transport company Uber, which they say is undercutting them and stealing their livlihoods.
They took to the streets of Guadalajara to block roads but factions of the protest angrily began to damage cars and shop fronts.
Security forces were sent to close down the main square where the protest had got out of hand, using smoke bombs to disperse the crowd.
Footage shows crowds of men fighting each other in the streets and riot police behind shields.
The governor of the state, Aristoteles Sandoval, has warned that although citizens have the right to protest, violence will not be tolerated.
He said: "We are in favour of the freedom of expression and the right to protest, but we will not permit disorder.
"I have instructed security forces to act at the moment that people bring disorder to the city with the full weight of the law in respect of the rights of the general public."
Directors of the taxi syndicates are currently in negotiations with local legislators to try and regulate the activity of Uber.
