Four people have been arrested, including a 16-year-old boy, after police seized a 'large quantity' of Class A drugs in a raid on a Norwich home.

Police raided the home in Riverside Road yesterday afternoon, seizing the drugs, cash and mobile phones.

A 19-year-old man from Surrey, a 16-year-old boy from Luton, a 20-year-old woman from Norwich and a 28-year-old woman from Ipswich were arrested on suspicion of supplying a controlled drug.

All four have since been released under investigation whilst enquiries continue.
