The coroner also reminded the jury about evidence from residents at Northwood Road and Premier Drive close to where Noah disappeared in north Belfast.

Both areas adjoin waste land leading to the entrance to the tunnel system where Noah’s body was found.

Some residents indicated that they were aware of local access to the waste land where the tunnel entrance is located.

Stormont’s Department for Infrastructure (DfI), which maintains the tunnel system, has been criticised at the inquest about safety measures at the site.

DfI witnesses informed the inquest previously that the department was satisfied with the safety measures around the culvert entrance.

Their evidence also stated that access could only be gained to the site by approved maintenance staff, residents in the immediate area, or if members of the public trespassed.

The coroner outlined to the jury how some expert witnesses disagreed on issues about safety at the site.

Mr Justice Rooney also reminded the jury about how some of the searchers who examined the culvert entrance for the first time shouted down the tunnel.

He said they called out “Hello”, paused to wait for any response, and then called again, “Hello, Noah”.
