The ex-Tory prisons minister was found dead at her home after sustaining serious injuries.
A 26-year-old man arrested on suspicion of murdering former MP and MEP Ann Widdecombe has been released from custody and is no longer part of the investigation, police said.
The ex-Tory prisons minister was found dead at her home in Haytor on Dartmoor on Thursday after sustaining serious injuries.
Miss Widdecombe, who was 78, later became a Brexit Party MEP and subsequently a Reform UK spokeswoman.
On Saturday, Devon and Cornwall Police confirmed the man’s release from custody, following his arrest on Friday.
Assistant Chief Constable Matt Longman said: “Our priority remains identifying those responsible and ensuring that all available evidence is thoroughly examined.
“Detectives continue to carry out numerous enquiries as part of the ongoing investigation and we remain committed to establishing the full circumstances surrounding the incident.”
He said the investigation was “moving at a significant pace”, adding: “We are deploying all of the necessary resources to find out exactly what has happened.
“I would appeal to anyone who may have information about this incident, however insignificant it may seem, to come forward and speak with us.
“We will release further information when we are able to do so. In the meantime, I would ask people not to speculate about what might have happened, particularly on social media.
“This is not only potentially harmful to our investigation but also deeply distressing for family and friends of Miss Widdecombe. The family have also asked for their privacy to be respected as they come to terms with what has happened.
“We have set up a Major Incident Public Portal for information, images or footage to be submitted to us. This can be found on our website.
“Information can also be passed anonymously to the independent charity Crimestoppers.”
