A man has been arrested following an incident in the Gaywood area of Kingâ€™s Lynn involving armed units.
Officers were called to Tesco in St Faiths Drive shortly before 7.40pm following reports a man had entered the store armed with a knife.
The man approached the customer services counter, demanded money and got away with a quantity of cash.
The suspect fled the store into the car park where he hijacked a car from a customer before fleeing the scene.
A number of resources, including armed units, were deployed to the area to search for the suspect.
Enquiries led officers to an address on nearby Tennyson Avenue where a man was arrested on suspicion of two counts of robbery. The suspect was arrested at 8pm, just over 20 minutes after police were called about the incident.
The 31-year-old has been taken into custody at Kingâ€™s Lynn Police Investigation Centre where he will be questioned.
The car stolen from Tesco was found nearby and a knife has also been seized by police.
Detective Sergeant Pete Jessop said: “Fortunately no one was injured during this incident but as this happened in a supermarket it would have understandably caused concern among members of the public.
“Officers were helped by several members of the public who provided information allowing police to swiftly detain the suspect, safely resolving the incident.â€
“Weâ€™re still keen to hear from witnesses and anyone with information should contact Kingâ€™s Lynn CID on 101.â€
