There can be absolutely no excuse for such violence and we will do everything we can to bring those responsible to justice— T/Detective Superintendent Carl Foster
A large police presence remains in the town while investigations are carried out to establish the full circumstances of the incident and identify those responsible.
Police said additional patrols will take place in the town over the coming days.
T/Detective Superintendent Carl Foster from the Bedfordshire, Cambridgeshire and Hertfordshire Major Crime Unit, said: “This was a horrific incident which has resulted in two young men losing their lives and a third suffering very serious injuries.
“I understand how concerning this will be for residents, however from what we know so far we believe this to be a contained incident with no wider ongoing threat to the public.
