Detectives are investigating the death of a four-week-old baby boy in Blackpool.
Two people were arrested on suspicion of manslaughter and child neglect after officers were called to a suspicious death on Rydal Avenue.
The pair, a 33-year-old man and a 30-year-old woman, were taken into custody on Boxing Day following the death of the baby boy.
Paramedics were called to the house, who then alerted police at around noon. The boy was taken to Blackpool Victoria Hospital where he was pronounced dead.
The two people arrested have since been bailed until June. A post mortem is due to take place tomorrow.
