A 33-year-old man has been arrested who police believe is linked to the death of a three-month-old baby boy.
Police received a report on Friday afternoon from the ambulance service that a baby was injured in a unit in Dorset, England.
The child was taken to hospital but died the next day.
“I can confirm that the tragic death of this young boy is being treated as suspicious and a murder investigation, led by the major crime investigation team, has been launched as a result,” said Detective Inspector Richard Dixey.
“A 33-year-old Bournemouth man has been arrested on suspicion of murder and he continues to assist police with their inquiries.”
“Police are not looking for anyone else in connection with this incident.”
A post-mortem examination will take place next week.
