NORWALK — A Norwalk mother is suspected of being high on PCP when she picked her child up from school on Wednesday, police said.

School officials told police that Carla Hall, 40, was acting erratically when she picked the child up from Columbus Magnet School around 3:30 p.m. Wednesday.

Hall, who was on foot, was approached by officers a short time later near the intersection of South Main and Concord streets. Police said Hall refused to stop when officers approached.

When Hall continued to ignore commands, police said, officers tried to physically stop her, which led to a brief struggle. Police said during the struggle, 10 glassine bags containing suspected PCP fell from Hall’s purse.

Hall was placed under arrest, and the 8-year-old child was given to Hall’s mother. The state Department of Children and Families was notified of the incident.

Hall was charged with possession of narcotics, possession of a controlled substance, possession of a controlled substance within 1,500 feet of a school, risk of injury to a child and resisting arrest. She was held on $15,000 bond and given a court date of Sept. 27.
