Neighbours have described their shock and sadness after police launched a murder probe following the death of a newborn baby in Ipswich.

A huge police presence swooped on Wilbury House in Norwich Road at about 12.35pm on Saturday afternoon after receiving reports of an infant being found outside a property.

Suffolk police later confirmed the baby was declared dead at the scene, despite the efforts of paramedics.

The death is being treated as unexplained and is under investigation.

The baby's sex has not yet been revealed by police.

Two men and a female were subsequently arrested on suspicion of murder in connection with the incident and taken into police custody for questioning.

The building was surrounded by a number of police cars and vans on Saturday afternoon, with a police cordon put in place to seal off the driveway.

A police dogs unit and a forensics van arrived later in the afternoon.

The cordon remained in place outside Wilbury House on Sunday morning.

A neighbour, 70, said he was lost for words upon hearing a baby had been found dead.

He added: "What can you say? This is devastating.

"Whatever can you say? I’ve been born and bred in this town. I’ve never heard of anything like this.

"I will go home now and it will bring tears to my eyes. I’m a parent. My god. I just don’t know what to say. That child could have grown up and had children."

A 24-year-old who lives at the house said: "Last night when I came back from work I saw officers and they started asking me my name and what my room number is and I told them."

He added: “I was shocked when I found out what happened. This is not good news, this is a human life.”

A 23-year-old neighbour said: "That’s a baby. I walked out yesterday with my dog and saw all the police and I thought it would be something to do with drugs because that’s common these days.

"It's scary."

Detective Chief Superintendent Jane Topping, of Suffolk police, has urged members of the public not to speculate on the incident online.

She said: “This is a very sad and distressing incident and, at this time, our investigation into the circumstances surrounding the baby’s death is in its early stages.

“I would urge people not to speculate on social media as to the circumstances of this tragic event.”
