The escape of Guzmán triggered a wide-range manhunt. According to Mexico's National Security Commissioner Monte Alejandro Rubido García, the manhunt was instituted immediately in the surrounding area by putting up several checkpoints and air searches by helicopter. The entire prison was put on lockdown and no one was allowed to enter or leave. The search was then extended to other federal entities: Mexico City, the State of Mexico, Morelos, Puebla, Guerrero, Michoacán, Querétaro, Hidalgo and Tlaxcala. However, most of the military officers involved in the search were sent to the State of Mexico. The Mexican government also issued an international warning to prevent Guzmán from escaping the country through airports, border checkpoints, or ports. Interpol and other security organizations were alerted to the possibility of him escaping into another country. Flights at the Toluca International Airport were cancelled, while soldiers occupied parts of Mexico City International Airport. Out of the 120 employees that were working at the prison that night, eighteen that worked in the area of Guzmán's cell were initially detained for questioning. By the afternoon, a total of 31 people had been called in for questioning. The director of the prison, Valentín Cárdenas Lerma, was among those detained.
