Five men have been arrested in Norwich after four men were found with stab wounds on Wednesday evening.
The victims were all taken to the Norfolk and Norwich university hospital for treatment. Two of the men are in a critical condition while the other two men have serious but non life-threatening injuries.
Norfolk constabulary said they were called to a property in Hemming Way shortly after 5pm after reports of a stabbing.
Officers found a man in his 20s inside the property with knife wounds.
A further call was received about 15 minutes later from the ambulance service reporting that three men had been found on Marriott’s Way with stab wounds.
A number of cordons have been put in place in connection with the incident and although inquiries are in their early stages, officers are treating the stabbings as an isolated incident and do not believe there is a wider threat to the public.
Anyone who witnessed anything should contact Norwich CID on 101 quoting incident 338 和 27 十月.
