Two people have been arrested after a fatal stabbing in Norwich.
Officers from Norfolk constabulary were called to Vale Green shortly before 7pm on Friday after reports that a man in his late teens had been stabbed.
The man was treated by paramedics but was pronounced dead at the scene. His next of kin have been informed.
Police said a man in his 40s and a woman aged in her 30s were arrested shortly afterwards in connection with the incident.
The woman was taken to Great Yarmouth police investigation centre and the man to Wymondham police investigation centre. They will be questioned in due course.
