MEXICO CITY, Oct. 19 (Xinhua) -- Police arrested an employee of a public kindergarten in Mexico City after accusations from some 20 parents that he sexually abused their children, the Office of the Attorney General said Friday.

The employee, who authorities said worked in educational support at the school, was detained in Ecatepec, a suburban municipality in the State of Mexico.

He was arrested after a judge issued an order of apprehension for pedophilia.

Parents of children attending the Marcelino de Champagnat school went public on Tuesday, blocking several streets in protest in the western part of the city to get the attention of the authorities.

During the protest, the parents said they had information that the employee had committed acts against 37 boys and girls. Authorities, however, have not confirmed that number.

The employee was suspended from his job as soon as the first complaint was made by a parent on Oct. 8, according to authorities.
