Peterborough's former Toys R Us store in Bourges Boulevard has gone up in flames.
Eight fire crews have been battling through the early hours of the morning to put out the blaze , with the last firefighter only leaving the scene shortly before 5am.
The fire was first reported at midnight and could be seen from a distance.
Police closed Bourges Boulevard between Westfield Road and Mayor’s Walk as firefighters from both Cambridgeshire and Lincolnshire tackled the blaze.
The road reopened at around 5am.
A Cambridgeshire Fire and Rescue Service spokeswoman said the cause of the fire has yet to be determined.
One crew will return to the scene later this morning to reinspect the site.
The spokeswoman said there were no reports of any injuries.
The store closed last year after the retailer went into administration.
