Culiacán (dpa) - Mexican security forces have stopped the arrest of a son of former drug lord El Chapo because of massive opposition. There were at least eight dead. Ovidio Guzmán López, wanted for narcotics trafficking in the US, was identified yesterday in a house in the city of Culiacán, according to the government. Then heavily armed gangsters appeared - they probably belonged to the Sinaloa drug cartel of "El Chapo". The approximately 30-strong unit of army and National Guard was reportedly in the minority and therefore withdrew.
