A man previously arrested after the tragic death of a newborn baby in Southampton is no longer under investigation, police have said.

Neighbours at Millbrook Towers were left speechless after emergency services were called to the tower block on the morning of Saturday, January 6 to the sudden death of a baby.

The air ambulance was called at around 8.20am and landed at nearby Mansel Park with police joining them ten minutes later.

Two doctors and specialist paramedics from the air ambulance assisted the ambulance service and the bay was rushed to hospital by road.

The baby boy, who was born on Christmas Eve, was pronounced dead despite the best efforts of paramedics.

Following this two people, a 33-year-old woman and a 24-year-old man, both from Southampton, were arrested on suspicion of causing or allowing the death of a child and neglect and were bailed.

But police have now confirmed that the Southampton man is no longer under investigation.

Hampshire police released no further details on the decision.

The baby’s death sent shockwaves through the community with many leaving flowers outside the front door of the flat on Windermere Avenue.

Four bouquets, a note reading ‘Fly High Baby Boy’, two blue teddy bears and a candle were left outside a door.

Mum Lauren Burnham, 29, a nursery practitioner, had previously said: “I had heard that it involved a baby, but we had no idea that this is what it was.

“We had some people come knock on our doors, but we didn’t expect anything so severe. Such a young soul and so vulnerable, it's heartbreaking. It makes me feel a bit sick.”

Her partner, Luke Childs, 30, a worker at B&Q, added: “I am speechless, and I don’t really know what to say.

“That this is something that happened in this block and to think it happened so close to us is quite unbelievable.”

A 32-year-old mum who has lived in the flats for 10 years said: “It is awful.

“I have lost a little one for myself and I know the pain of losing a child. It makes me shiver to hear this happened.”

The 33-year-old woman remains on conditional police bail until July 6 while police enquiries continue.
