On 3 and 4 May 2006 more than 2,500 federal, state and municipal police participated in an operation to end the protests led by local organization People's Front in Defence of the Land (Frente de Pueblos en Defensa de la Tierra, FPDT), in Texcoco and San Salvador Atenco, Mexico State. The police operations resulted in the arrest of 207 people, two people killed, and injuries to dozens of protesters and police officers as well as several police officers taken hostage. Amnesty International published the report, Violence against women and justice denied in the Mexico State, (AI Index: AMR 41/02/2006), documenting the sexual violence suffered by at least 26 of the women that were arrested.
More than fifty people continue to face criminal charges in relation the protests on 3 and 4 May 2006, thirteen of which remain in custody. On several occasions Amnesty International has expressed concern about the serious irregularities in judicial proceedings that have violated the right of the accused to a fair trial.
The Mexican National Supreme Court of Justice is undertaking a non jurisdictional enquiry into the events.
