Mexico's National Human Rights Commission, or CNDH, said it was investigating the case of a Tzotzil Indian boy who was "insulted" by an official in the southeastern state of Tabasco and which has sparked indignation across the country after the airing of a video that captured the incident.

The humiliation of the boy occurred Monday in downtown Villahermosa, capital of Tabasco, when the public servant forced Manuel Diaz to throw the candy he was selling on the ground and then grabbed the kid's packs of cigarettes with the argument that they were being sold by a minor.

The moment was filmed and the video went viral on YouTube, visited by more than 1 billion unique users each month, and spread a wildfire of indignation among Mexicans.

When the case went public, personnel of the CNDH, Mexico's equivalent of an ombud's office, "rushed to the scene to look for the victim and collect testimonies," the institution said in a communique.

Tabasco's Attorney General's Office said in a communique that it has started an investigation for "the possible commission of the crimes of abuse of authority and robbery with moral violence against the minor Manuel Diaz.

It also issued an order to find and present in court Juan Diego Lopez Jimenez, dismissed from his position in the municipal government after the scandal broke out, and Carmen Torres Diaz, who also appears in the video, for her suspected responsibility for the abuse of an indigenous minor.

The boy's aunt, Maria Diaz, told authorities that a week ago she took him to Villahermosa from the Tzotzil town of San Juan Chamula, Chiapas state, where he lives with his grandparents.

She said he was on vacation and wanted to earn some money to buy school supplies.

The CNDH said it will continue the investigation "in order to protect the victim, who apparently returned to Chiapas after the aggression." EFE
