Mazatlán Prison Riot Leaves 10 Dead, Including Visiting Child, and 16 Injured
A riot at El Castillo prison in Mazatlán, in Mexico's Sinaloa state, left 10 people dead and 16 inmates injured Thursday, authorities said. Nine of those killed were prisoners; the other victim was a family member visiting the facility, identified by media reports as a child.
Sinaloa's Public Security Secretariat said the injured inmates were taken for medical care. "Nine people deprived of their liberty, one family visitor and 16 more inmates were injured," the agency said in a statement.
Authorities said security forces intervened to stop the violence and that the prison was under control. "The penitentiary is currently under control, and authorities remain present to guarantee the security of the facility," the statement said, according to N+.
The violence broke out during family visiting hours. Local reports described gunfire inside the prison, prompting a deployment of state and federal security forces. The state agency did not publicly explain what triggered the riot or how the victims died.
The Army, National Guard, navy and state security forces entered the prison to restore order. Mexico's federal security cabinet said the facility, which houses about 1,800 inmates, was under control. Sinaloa authorities suspended visits scheduled for Thursday as a precaution and said prison social workers were contacting victims' relatives.
Thursday's riot followed another deadly incident at El Castillo. On Sept. 24, two inmates died after a confrontation in the prison's workshop area, La Jornada reported, citing Sinaloa's public security authorities.
The deaths also come as Sinaloa continues to face violence linked to a power struggle between factions of the Sinaloa Cartel. The state has been affected by fighting between groups associated with the sons of Joaquín "El Chapo" Guzmán and followers of Ismael "El Mayo" Zambada. Authorities have not said whether the prison riot was connected to that conflict.
The Sinaloa prosecutor's office is investigating the incident. Officials have not announced arrests or released a detailed account of how the violence began.
