See The 'World’s Most Criticized Prison' Housing 4,000 Tattooed Gangsters Who Will Never Go Home (PHOTOS)

Thousands of tattooed suspected gang members have been sent to a sprawling new prison in El Salvador that they will ‘never return’ from.

More than 65,000 suspected gang members have been arrested since March last year amid a government crackdown in the Central American country.

It came when an eruption of gang violence left more than 60 dead – including street vendors, bus riders and marketgoers – in the nation’s bloodiest day since the civil war 30 years ago.

The 40,000-capacity Center for the Confinement of Terrorism in Tecoluca, San Vicente, was purpose-built to relieve the increasingly overwhelmed prison system.
