Crimes of the Zetas - Mexico's most notorious cartel - Telegraph Murder of American officials Two American immigration officials, driving along a main road from Mexico City to Monterrey in February 2011, were attacked by the gang. Special Agent Jaime Zapata, 32, died and a second agent, Victor Avila, was wounded as they stopped at a roadblock on a four-lane highway. The attack was the most high profile attack on American officials since the 1985 torture and murder of Enrique Camarena, a US drugs official.

In August 2011 members of the Zetas stormed the casino in mid-afternoon, doused the building with petrol, and set it alight. Fifty two people died in the blaze. Hanging bodies In Miguel Treviño Morales' hometown of Nuevo Laredo, police in May 2012 found 23 bodies hanging from a bridge or decapitated by the City Hall. Highway murder Less than ten days after the bodies were left hanging from a bridge, security forces in Nuevo Laredo found 49 bodies dumped in the middle of a main road. Identification was hampered by the fact that the victims had their heads, hands and feet chopped off. Body snatching Heriberto Lazcano, leader of the Zetas, was killed in a shoot out with Mexican soldiers in October 2012. However, in a surreal twist, his corpse was snatched from the morgue by his men hours after his death. The military were reportedly unaware of the "value" of the dead man until the funeral home was stormed by armed men, who carried off "The Executioner" in his body bag.

Horse racing Miguel Treviño Morales is a horse racing fanatic - so he concocted a scheme to launder $16 million (£10.5m) of drug money in just over two years through racing stables run by his brother, José. The brothers bought over 400 quarter horses, set up a breeding and training stables in Oklahoma, and within three years won some of the industry's biggest prizes. The horses were given tantalising names - such as Number One Cartel, The Hitman, Mr Ease Cartel and Mr Piloto. In 2010 the stables paid more than $1m for two broodmares, which caught the eye of the authorities. The ranch was raided in July 2012, and Jose was arrested alongside his wife and staff. Miguel was described during the May 2013 trial of his brother as an active participant in the scheme, who kept a listing of the horses' prices and names on his mobile phone. A court in Texas convicted José, 46, of buying racehorses to hide illegal drugs profits, and he is facing 20 years in prison. Feud with Anonymous In November 2011 the Zetas kidnapped a member of hacking collective Anonymous. The hackers vowed to publish the details of all known members of the Zetas unless their colleague was released; the Zetas freed the man several days later. A new branch of Anonymous has since been formed in the town of Acuña, Coahuila state, which is publishing online the photos of homes and businesses they say belong to the Zetas, in an attempt to drive the cartel from their town.
