Mrs Robinson said the couple were ‘arrested straight away at the hospital’ and held in custody.
Speaking from her home in Tamworth, she added: ‘They are devastated ... They are not hiding anything. The police are quite willing to accuse the parents who would never do anything to their children.’
She went on: ‘I think [their arrest] is a formality. They have to investigate it. It’s [as if] because you weren’t with your child at the time you’re guilty, but that’s not always the case.’Indeed it isn't.
West Midlands Police has issued a statement confirming the child was aged 18 months and fell from the seventh floor.
The force said: "Police are investigating after a child fell from the seventh floor of a block of flats in Great Hampton Row, Hockley, at around 11.55am yesterday (Monday).
"The child, aged 18 months, tragically died at the scene.
"The death is currently being treated as unexplained and a post-mortem examination will take place in due course.
"The coroner has been informed."Odd how they haven't arrested anyone. Wonder why?
