Mexico drug arrests leave prisons crowded and violent

By Miguel Angel Gutierrez

MEXICO CITY (Reuters) - The rounding up of thousands of suspects in Mexico's drug war has left the already unruly prison system overwhelmed with jailbreaks and struggling to contain deadly riots between inmates from rival gangs.

Dozens of violent clashes have rocked jails this year and a stream of inmates have escaped. Last month drug hitmen dressed as police screeched up to a northern Mexico prison in a convoy of vans and freed 53 prisoners who were seen on security cameras pouring into the street.

The chaos is posing another security risk for President Felipe Calderon, who has made crushing drug violence the centrepiece of his presidency.

Mexican media count 22 jailbreaks this year and some 40 prison feuds, fuelled by guns smuggled in by visitors and lax or corrupt guards who let prostitution and drug peddling go on within prison complexes.

April alone saw 19 riots in jails in Mexico City, where wealthy inmates bribe guards for spacious cells with televisions, while others sleep on bare floors in crowded conditions, Mexico's Human Rights Commission says.

Guards have made inmates strip naked and lie down in lines in prison courtyards as they attempt to restore order.

"We have a flashpoint with corruption, huge overcrowding, extortions and things going in that shouldn't," Patricio Patino, deputy head of the federal prison service, told Mexican radio.

Soldiers and police have rounded up some 40,000 drug gang suspects since Calderon launched his army-led drug crackdown in late 2006, earning praise from Washington and scoring points with voters fed up with years of Mexico being used as a route for trafficking South American cocaine to the United States.
