Six women have been arrested in connection with the suspicious death of a one-year-old boy at a nursery.
West Midlands Police said a criminal investigation was launched after the toddler died at Fairytales Day Nursery, in Bourne Street, Dudley, on 9 December last year.
The nursery was closed by Ofsted along with other linked premises on 14 December after the watchdog said "children may be at risk of harm" and suspended its registration.
The force said three women aged 20, 23 and 50 were arrested on 16 December on suspicion of gross negligence manslaughter and later bailed.
