A man in his 40s has been arrested on suspicion of assault after an incident at a supermarket in which a woman suffered a head injury.
Police were called to Sainsbury's at Longwater in Costessey at 10.58am on Monday to reports of a disturbance.
"Emergency services were in attendance and a man was arrested at the scene," a police spokesperson confirmed.
The East of England Ambulance Service (EEAST) confirmed it sent an ambulance and a rapid response to the vehicle.
"One patient was transported to Norfolk & Norwich University Hospital for further care," an EEAST spokesperson added.
It is understood the man arrested threw jars of sauce at the victim, which hit a Perspex screen and caused a loud noise.
The noise and the sauce spillage caused concern among witnesses and led to some on social media wondering if a gun had been fired, but no firearm was involved.
