A West Palm Beach grandmother told officers her son and his wife were doing drugs while her grandchild sat in a bathtub unsupervised, the Palm Beach Post reports.

The couple defended themselves and told officers the child was supervised: They were just having sex in the bathroom while their child was in the tub.

Robert Anthony Scott, 26, and Angela Noble, 25 face charges of child abuse and child neglect for leaving their child unsupervised while in a bathtub, according to an arrest report.

Palm Beach County Sheriff officers arrested the couple early Tuesday morning after they received a call from Scott’s mother. The couple live with Anthony’s mother in West Palm.
