An investigation has begun focusing on the storm drain network in north Belfast where the body of Belfast schoolboy Noah Donohoe was found.
Police are working with the Health and Safety Executive and Public Prosecution Service looking into the accessibility of the drain.
The teenager’s body was found in the storm drain on 27 June last year.
He had been missing for six days.
Police say this investigation regarding access to the storm drain network is separate to the ongoing probe.
The investigation will focus on the network in Premier Drive/Northwood Road in North Belfast, which is owned by the Department for Infrastructure.
Police have informed the Donohoe family of the development.
