July 10 (UPI) -- British police announced Friday that they arrested a man in the slaying of former Member of Parliament Ann Widdecombe, who was found dead in her home Thursday.

Devon and Cornwall Assistant Chief Constable Matt Longman said at a press briefing a 26-year-old man was arrested on Friday afternoon at a home in Newton Abbot, England, on suspicion of the murder of Widdecombe, 78, who was killed in Dartmoor, Devon. The two areas are about 15 miles apart. The suspect is a British national, police said, and the slaying was not believed to be an act of terrorism.

Longman said there isn't evidence that the killing was politically motivated, though it is early in the investigation.

"Too early for me to comment further on that at this time," Longman said.
