Workers were evacuated from an office in Norwich city centre after a battery leak.
The building was sealed off after a maintenance worker discovered a battery leak.
Fire crews were called to Norfolk Tower - a former Aviva office - in Surrey Street just before 2.30pm today (Friday).
Firefighters from Sprowston, Carrow and Earlham were called to the building.
Initial reports suggested it was Aviva staff who were evacuated from the office.
However, the insurance giant is no longer based there and it is believed the staff who were evacuated were from marketing company Balloon Dog.
Fire crews put on protective clothing to go into the building and remove the battery, while police also attended.
