Questioning continues over Birmingham boy's murder
Police have been given extra time to question a 22-year-old woman and 29-year-old man held on suspicion of the murder of a two-year-old boy.
The pair, understood to be the boy's mother and her partner, were arrested after the boy was pronounced dead at a Birmingham hospital on Sunday.
He had been taken to hospital from an address in Ward End.
A post-mortem examination indicated the child died as a result of "non-accidental injuries", police said.
A spokeswoman for the West Midlands force said police now have until late on Thursday evening to continue questioning the pair.
She said: "The couple remain in police custody having been granted warrants of further detention."
The child has not yet been named.
