POLICE have today arrested a second person in connection with the death of a four-week-old baby in Ipswich.

Officers today arrested a 22-year-old woman as part of their investigation into the death of the baby boy.

A Suffolk police spokesman said the arrest took place this morning and added the woman was being held at a police station in Suffolk.

Today's arrest follows the arrest on Saturday of a 31-year-old man in London Road, Ipswich, on suspicion of murder and grievous bodily harm.

That arrest came soon after paramedics were called to Lanercost Way in Ipswich at about 8.30am on Saturday following a report of a baby in need of treatment. The baby died in Ipswich Hospital a short time later.

Neighbours reported hearing an ambulance arrive at the address at about 8.40am and soon after police put a cordon around the house.

The baby's mother was also taken to Ipswich Hospital where she was treated for injuries which police said were not life threatening.

They said the baby's death was being treated as unexplained and enquiries were continuing.

Today officers were granted an extension to the custody warrant for the 31-year-old man, which will allow them to continue questioning him until 5pm tomorrow.

The police spokesman said: “In relation to the 31-year-old man arrested in connection with the same incident, police have been granted a further warrant of detention by Ipswich magistrates to continue holding him at Ipswich police station until 5pm tomorrow.”
