Mexican prison guards ‘let out inmates to kill’
After carrying out the killings the inmates would return to their cells, the attorney general’s office said in a revelation that was shocking even for a country wearied by years of drug violence and corruption.
“According to witnesses, the inmates were allowed to leave with authorisation of the prison director... to carry out instructions for revenge attacks using official vehicles and using guards’ weapons for executions,” office spokesman Ricardo Najera said at a news conference.
