HOUSTON -

A woman has been accused of abusing her adopted daughters.

Onyeka Lucy Asonye, 46, has been charged with two counts injury to a child under the age of 15.

Houston police said they were called out to a southwest Houston day care facility in early March because employees noticed injuries on two girls.

Investigators said that a 3-year-old girl had a large bump on her forehead and one of her eyes was swollen and shut. She and her 4-year-old sister were examined and multiple bruises and scars were found on each girl, police said.

Doctors examined the sisters and found signs of abuse, including blunt abdominal injuries, police said.

Detectives said they spoke to Asonye, who said she adopted the girls from Nigeria. She confessed to "flogging" the girls with twigs and branches, police said.

"I wasn't trying to abuse them," police said Asonye told them. "I want the best for them and myself that is the only reason I beat them."

Asonye is being held in the Harris County Jail with bond set at $20,000.
