Armed police were called to Norwich train station following reports of a man armed with a knife.
Officers arrested a man in his late 40s yesterday (Sunday) on suspicion of possessing an offensive weapon and public order offences.
Police were initially called out to the Norwich Road area of Rackheath, north east of the city, shortly after 5.30pm.
But a police spokesperson said enquiries led to armed officers relocating to Norwich train station.
Norfolk Constabulary said the man had been taken to Wymondham Police Investigation Centre for questioning, where he remains in custody.
Julia Turner, landlady of the Sole and Heel pub in New Rackheath, said she saw 'four or five' police vehicles patrolling the area.
'They turned up around 6pm and were driving around here for about half an hour,' she said. 'They then went haring off towards Norwich just before 7pm.'
