A teenager is due to appear in court this morning following three stabbings at a party last weekend.
Bailey Bowen, who is 18 and of Brickhill Drive, Bedford, has been charged with the attempted murder of one of the victims.
Three men, all in their early 20s, were stabbed at a barn party at Begwary, near St Neots, at about 2.30am on Sunday.
A second man, who was arrested on Sunday, has been released on police bail while a third continues to be questioned by police.
About 200 people are thought to have attended the party.
Det Insp Jerry Waite said: "Clearly there were a large number of people at this event who may or may not have known the victims or offenders but we are keen to trace anyone who was present and could help the police investigation into what happened."
