Detectives have begun searching the garden of a property for human remains after reports of the death of a child.
The move follows information given to police regarding a death at the home in Clarence Road, in the Handsworth area of Birmingham in 2020.
A man aged 40 and a woman, 41, have been charged with neglect and are on bail for causing or allowing the death of a child.
West Midlands Police said the man had been remanded after appearing in court.
The pair were arrested on Friday and the man appeared at Birmingham Magistrates’ Court the same day.
The woman was due to appear before the same court on Tuesday.
People who currently live at the property are not connected to the investigation, the force said.
Det Insp Joe Davenport said: “We have acted swiftly on information and our inquiries are ongoing to establish exactly what has happened.
“I understand that this will come as a shock to the local community but I would ask you not to speculate on the circumstances.”
