A woman has been arrested on suspicion of perverting the course of justice in connection with a false allegation of rape.
The claim, which turned out to be false, was made in Daventry on April 23.
As a result of the rape allegation, a 26-year-old man was arrested and subsequently released without charge when the allegation was withdrawn.
The woman was arrested in the Somerset area earlier this week and interviewed by Northamptonshire Police officers.
She has been released on police bail while the investigation into the allegation of perverting the course of justice continues.
