Two teenagers have been arrested on suspicion of murder after a six-week-old baby died in Southampton.
Police were called to a home in Defender Road, Peartree, at about 05:00 GMT on Sunday after reports of a baby boy needing medical attention.
The child was taken to Southampton General Hospital where he was pronounced dead a short time later, Hampshire Constabulary said.
An 18-year-old woman and a 16-year-old boy were arrested.
The suspects, both from Southampton, are being held in custody.
