Officers were called by a member of the public who found an "unknown item wrapped in plastic" at Kersal Dale, Salford, Greater Manchester Police (GMP) said.

Pathologists and detectives at the scene confirmed it was human remains, which are yet to be identified.

They were found at about 5.50pm on Thursday in a secluded woodland area.

An extensive police scene has now been put in place at the largely wooded reserve, which sits north of Manchester city centre and covers around 32 hectares of countryside, according to its website.

Detective Superintendent Lewis Hughes, from GMP's serious crime division, said: "I want to assure the local community that although this is a disturbing and unsettling find, we have a large visible presence in the area to complete inquiries, provide reassurance and to listen to any concerns."

The scene at the reserve, which is closed to the public, "is likely to remain for some time" while police "work to unravel what exactly has happened," he added.

Anyone who may have relevant information is being urged to speak to the police.

DS Hughes said: "We know that behind this discovery there will be a family who have lost a loved one, and we want to make sure they are supported as quickly as possible.

"Anyone who thinks they may have witnessed something suspicious in the Kersal Dale area over the last few days could be key to unlocking what happened.

"I would ask that anyone who has any information that may be relevant to our inquiries, no matter how big or small, comes forward."
