Human remains found in a park could be from someone who was murdered several years ago, it has been reported.
Police have been investigating a site in Hull’s Brackley Park following the discovery 12 days ago.
A police cordon has expanded as forensic investigators investigate a number of different locations associated with body parts.
Hull Live reported that one theory being considered by officers is that the victim may have been hit by a train from the nearby railway line.
However, the incident is thought to have happened months or even years ago. It is not known whether the police have been able to identify the victim.
The investigation is being led by the British Transport Police due to its proximity to the railway. The land to the west of Brackley Park is owned by Network Rail.

Police were first called to the scene at 6 p.m. on December 7 after “reports of human remains found”.
On Friday, there were four separate crime scenes with tents behind a cordon in the park. Crime scene detectives in white forensic overalls were seen at the scene.
Researchers had to work in cold weather, with temperatures dropping to -5°C at night.
The area closed to the public is popular with dog walkers, families and cyclists.
Britain’s Transport Police said it is only examining the remains of one person.
In a December 13 statement, police said: “We are still searching the area. It is believed to be the remains of one person – and detectives are following a number of inquiries to identify them.”
A mother who lives close to the park, using only her name Nicola, said: “We have lived here for 11 years and walk our dogs in that park every day, if not twice a day.
“It comes as a shock that something like this is happening on our doorstep.
“On Wednesday afternoon we were actually out with the dogs when we saw a person lead a police officer to that area – that must have been what it was for.
“It’s a lovely place for families here, but the area has had problems before, especially in the summer.
“There will be kids with motorcycles who are anti-social or people who occasionally use drugs, but most of the time it’s nice and quiet.”
