Two men and a woman were arrested outside a filling station on Yarmouth Road in north Lowestoft on Monday, February 15.
Police responded to reports about a suspected stolen vehicle, which was subsequently pulled over outside the service station in Gunton.
A man in his 20s was initially arrested on suspicion of robbery, false imprisonment and possession of a controlled drug.
