A three-year-old boy who was found dead in a lake following a huge search had left a play area “through a gap in the fence”, an inquest heard.

Noah Woods became separated from a relative after visiting a playground in Merriam Close, Brantham, on the afternoon of September 15, Suffolk Police said.

Around 1,300 members of the public joined a search to find the youngster, who police said was non-verbal, partially deaf and had been undergoing an assessment for autism.

Met Police divers recovered his body from a lake, known locally as Decoy Pond, on the afternoon of September 16 and Suffolk Police said his death was not being treated as suspicious.

An inquest into Noah’s death was opened and adjourned in Ipswich on Friday.

Detective Chief Inspector Matthew Connick told the hearing that on September 15, Noah, of East Bergholt, Suffolk, was being “looked after by relatives and this was part of a normal routine for Noah”.

He said they walked to an under-fives play area and CCTV footage in the park “showed Noah playing with his relative”.

The first CCTV footage was timed at 2.13pm and he was last see playing at 2.37pm, said Mr Connick, who added the CCTV “is motion-activated so doesn’t provide continuous footage”.

He said the relative, who was not named at the hearing, had provided a statement to police.

The officer said Noah “left through a gap in the fence leading to the memorial garden where he left through an open gate”.

He said Noah went in the direction of Decoy Pond and he was “being closely followed by his relative who was trying to keep up with him”.

He said the relative “shouted after him”, but after 200 metres Noah could not be seen.

“Police were called and a large-scale search operation began,” Mr Connick said.

He said Noah was found by a Met Police diver “approximately five metres from the bank and within submerged tree roots”.

He said the depth was estimated at 1.8 metres at that point.

A post-mortem examination at Addenbrooke’s Hospital mortuary in Cambridge recorded his medical cause of death as pending further investigation, Mr Connick said.

He said Noah’s death was confirmed at 4.31pm by paramedics and his identity was formally confirmed by his mother Charlie Peck at Ipswich Hospital that evening.

Assistant coroner for Suffolk Jyoti Gill said at the outset of the hearing, which was not attended by family: “I would like to express my deepest condolences to Noah’s family and friends and all those affected by Noah’s death.”

She said at the end of the six-minute hearing: “The inquest is adjourned to a date to be fixed in due course.

“Once again, my deepest condolences.”

Noah’s father Rhys Woods paid tribute to his son in a message shared on a community Facebook group last week.

He described Noah as the “sweetest and most innocent little boy, with nothing but love to give”, and added: “We are going to miss him so very much.”
