The arrest comes after blazes in large derelict buildings, including Trowse pumping station on Sunday. 

There were 42 firefighters called to the blaze at the grade II listed building with appliances from North Earlham, Carrow, Fakenham and Hethersett assisted by aerial ladder platforms from North Earlham and Great Yarmouth.

Crews were on site from just before 9pm on Sunday until close to 5am on Monday, with initial investigations of a potential arson held up due to the site being dangerous to enter.

Another of the fires linked was at a disused hospital in Thorpe St Andrew on Thursday, October 19.
