POLICE have arrested a 43-year-old man on suspicion of the murder of schoolgirl Nikki Allan.
He is currently in police custody helping detectives with their inquiries.
Nikki, who was seven, was found dead on October 8, 1992, in the then-derelict Old Exchange Building, near to her family home in Wear Garth, in the east end of Sunderland.
The investigation into her death has been ongoing for more than 21 years, and officers are making a fresh appeal for anyone with any information to come forward.
They are particularly keen to speak to anyone who lived in the Wear Garth area at the time of the murder or anyone who hung around or inside the Old Exchange Building.
In September 2013 officers from Northumbria Police’s major crime team worked with BBC Crimewatch to film a reconstruction of Nikki’s last movements.
Anyone who thinks they have any information that could help detectives with their inquiries is asked to contact police on 101, ext 69191.
