“At this time, our investigation into the circumstances surrounding the baby’s death is in the very early stages and we ask the public not to speculate about the case.
“There is a cordon in place on Norman Crescent in the Rossington area while our officers carry out their work, and therefore we are asking members of the public to avoid the area at this time.”
