Calderon tackles drug violence
Mexican president backs up law-and-order pledge by sending troops to violent state.
Ramirez also said authorities will also use search warrants and detention orders as well as detecting and shutting down locations where drugs are sold.
More than 1,500 people have died across Mexico this year in drug-related killings. About 500 have lost their lives in Michoacan state alone.
The majority of the victims have been members of rival drug gangs fighting a turf war.
Brutal killings
Drug cartels in the area are fighting for control of smuggling routes into the US. The drug trade from Mexico to its northern neighbour is currently estimated at about $10bn a year.
As well is the level of violence, it is the nature of some of the crimes committed that has prompted Calderon to act swiftly. Drug-related killings in Michoacan are known for their brutality.
The region has seen a string of decapitations as the gangs seek to intimidate those who oppose them.
A group of armed men recently burst into a crowded nightclub in the town of Uruapan, shooting their rifles in the air. Having told everyone to lie on the ground they then they rolled five severed heads on to the floor.
Calderon was elected on platform of law and order and seems determined to put his words into action and demonstrate that he is prepared to rule with an iron fist – and in order to combat the wave of violence in western Mexico.
