The government of the western state of Michoacan should take action to "repair the damage done" to about 20 schoolchildren who were strip searched at a public school where 180 pesos ($13.80) had been reported missing, the Mexican National Human Rights Commission, or CNDH, said.

State officials should "take the necessary measures" to help the victims by providing "medical and psychological assistance," the CNDH, Mexico's equivalent of an ombudsman's office, said.

The incident occurred on Sept. 23, 2011, when about 20 11-year-old students at the Club de Leones elementary school in the city of La Piedad were forced to strip because the small amount of money could not be found.

School officials initially threatened to call "the police to search them" and later forced the students to "remain seated, without moving, looking down and with their arms on their heads," the CNDH said in a statement.

When a search of the children's belongings did not turn up the money, principal Maria Dolores Reyes Estrada and a teacher made the children get naked and inspected them, the CNDH said. EFE
