Police use Taser in Norwich armed robbery arrest
Police officers used a Taser during the arrest of a man following an armed raid on a building society in Norwich.
Officers were called to the Norwich and Peterborough branch in Plumstead Road at about 16:50 BST on Monday.
A customer dialled 999 to report a man was demanding money from staff while holding a small knife.
Norfolk Police said a man seen acting suspiciously in gardens in Dugard Road an hour later was arrested in connection with the robbery.
A spokesman said a Taser was discharged during the arrest.
A quantity of cash was stolen in the raid.
The man arrested was 42 and will be questioned later by police.
Det Sgt Tom Smith, from Norwich CID, said: "Fortunately, no one was injured during the incident although staff have understandably been left shaken by this afternoon's events."
He said the prompt call from the customer had enabled officers to be despatched immediately, leading to the arrest.
"We're still keen to hear from any witnesses and I would urge people who may have been in the area at the time to come forward," he added.
