A teenager's bail has been extended for a second time after being arrested in connection with arson attacks at three high-profile city sites.

Beginning last year, a series of fires broke out at disused sites in the Norwich area, in Thorpe St Andrew and Trowse, sparking serious security concerns.

The fires began on July 22, 2023, when a fire broke out at a disused building on the May Gurney and Deal Ground site in Bracondale, Trowse - which is earmarked for nearly 700 homes.

There was another fire at a disused hospital in Thorpe St Andrew on October 19, before a third - at Trowse Pumping Station - on November 12.

But despite a teen being arrested just four days after the latest attack, no charges have been made and his bail was extended once already to January 20.

Now police have confirmed the teen has been re-bailed until February 16.

His bail conditions include a clause to not enter any derelict buildings and he was also given a curfew to stay home between 9pm and 6am.

Police are asking anyone with information or footage that could help the investigation to call 101.
