Officers were called to Sleaford Green on Thursday 21 April following reports that a man had suffered multiple stab wounds.
The victim, a man in his late 20s, suffered serious life-threatening injuries and was taken to the Norfolk and Norwich University Hospital for treatment where he remains in a stable condition.
Three teenagers arrested in connection with the incident have been questioned and released with no further action to be taken against them in relation to the serious assault.
