A Loudoun County woman was charged Thursday with attempting to poison her 1-year-old daughter on Halloween night, Leesburg police said yesterday.

Anita Sakyi of Leesburg was released on bond and is scheduled to appear in court tomorrow. She faces up to 20 years in prison if convicted.

Police said Anita Sakyi's parents brought her and the child to a hospital emergency room late Oct. 31 after being told that Sakyi had swallowed a small amount of a potentially poisonous liquid and served some to her daughter.

The girl was treated and released to her grandparents. Sakyi was held overnight for observation, police said.

Police spokesman Jeff Dube said he would not name the liquid until lab tests confirm its composition.

But he said police think it was an antiseptic that can be easily purchased.

Authorities think Sakyi was trying to commit suicide, Dube said.

"It looks like she may have some serious mental health issues," Loudoun County Commonwealth's Attorney James E. Plowman said.

Yesterday afternoon, a woman who said she was Sakyi's mother stood outside a brick townhouse in the 400 block of Baish Drive SE in Leesburg holding the smiling, plump baby, who wore a yellow sweat suit and sucked on her fingers.

The woman, who declined to give her name or the baby's, said that Sakyi is "depressed" and that the girl had not swallowed any "medicine."

"Her mother was vomiting, but she was not," the woman said, referring to the baby.

She said hospital tests found the baby had not ingested poison.

She said Sakyi and the child are in good health.
