The lead investigator into a case concerning the death of a toddler in Coventry said he is determined to find out what happened to the three-year-old.
Detective Inspector Chris Hanson is urging anyone with information about Mariam Alam's death to contact him.
The supermarket camera footage – which is available on the force’s YouTube channel – shows Mariam wearing a red flowery dress, white tights and a pink coat walking in front of her mother as they enter Lidl in John Wigley Way at 1pm.
They can be seen leaving five minutes later – but at around 1.20pm paramedics were called to the address in Fisher Road after the child collapsed. Despite the best efforts of medics, the toddler couldn’t be saved.
