The prisoners broke out of the jail in Nuevo Laredo late on Thursday or early on Friday morning. Security guards are being questioned on suspicion of helping the inmates flee, and prison director has gone missing.
Mexico’s prison system is struggling to cope with an influx of violent offenders arrested in the government’s campaign against drugs cartels.
Nuevo Laredo in Tamaulipas state lies just across the border from Laredo, Texas. Tamaulipas security chief Antonio Garza said the break-out – one of the largest in the country’s history – went unnoticed until guards carried out a routine head count.
Officials believe the inmates had escaped through one of the prison’s back gates, with the connivance of one or more security guards.
