A flat in Teeside which has been searched by police several times recently has now been boarded up, as the 25-year investigation to solve the murder of Sunderland school Nikki Allan continues.
Earlier this month, a man was also arrested at a nearby address in Stockton in connection with the murder. He has now been released and no charges have been brought.
In 2017 police discovered new male DNA in relation to the case and appealed for men involved in the investigation to come forward for DNA testing in order to be ruled out as suspects.
At the time, a Northumbria Police spokesperson said: “Nikki would have been 32 years old this year and it is utterly heartbreaking to hear from her parents and close family talking about what could have been for Nikki – she may well have had children of her own by now.
“Although the murder happened 25 years ago it is still very much an active case for Northumbria Police and we will continue to investigate until Nikki’s killer is brought justice.”
Nikki Allen’s body was found in a derelict building in Sunderland in 1992. She had been stabbed 37 times after disappearing from her home in Wear Garth.
Anyone with any information about Nikki’s death can speak to Northumbria Police’s major crime team on 101 ext 69191 or the independent charity Crimestoppers on 0800 555 111.
