Grimsby garden drain baby's post-mortem 'inconclusive'
Tests on the body of a baby found in a garden drain have proved inconclusive, police have said.
A plumber discovered the corpse on Thursday, after he was called to a property in Scartho Road, Grimsby.
Det Insp Christine Calvert said items found with the body suggested it had been "in situ" since a time "post 2013".
A post-mortem examination revealed the baby was a boy, but the cause of his death was undetermined, she said.
Further tests will be carried out.
Ms Calvert said the baby appeared to have gone to full-term.
