Lillie Adams, Ruben Sandoval and Perla Denise Sierra Duarte

PHOENIX — Phoenix police say three people have been arrested in an alleged child abuse case, in which a day care worker is accused of striking a 21-month-old boy with a broom handle.

Police said officers arrested 37-year-old Lillie Adams on Thursday on one count of child abuse after investigating a Feb. 17 incident in which the boy was taken to a hospital for treatment of an unspecified injury.

The owner of Brighter Angeles Learning Center and a director for the center were arrested the following day, and are accused of hindering prosecution and failing to accurately report an injury to law enforcement as required by law.

Police identified the owner as 51-year-old Ruben Sandoval and the director as 26-year-old Perla Denise Sierra Duarte.

Efforts to reach Sandoval and Duarte for comment on the allegations were not immediately successful Saturday.

The Maricopa County Sheriff's Office indicates Adams remained jailed Friday pending an initial court appearance, and a court website doesn't indicate whether she has an attorney who could comment on the allegation.
