A Norwich police officer finishing a night shift was assaulted in Guildhall.

Police have said the man was causing a disturbance and shouting at members of the public at 7.10am this morning.

PC Welch from Norwich Police said: 'The officer made himself known and the man stopped shouting abuse at the public.

'The male then punched the officer in the head and resisted, officers arrived on scene and arrested the male who is now on route to custody.'

The officer assaulted is now back in the station doing paperwork.
