A 29-year-old man, who police had been hunting in connection with the murder of a mother and her son in Lincolnshire, has been arrested.
Armed officers and several police vehicles were involved in the arrest at a farm in Hallington, near Louth.
Two, escorted a man wearing no shoes or socks and ripped tracksuit bottoms, into a police van at the back of a farm building.
The woman, aged 26, and her nine-year-old son were found fatally stabbed in Louth on Monday and police had issued an appeal to trace Boulton in connection with their deaths.
Lincolnshire Police’s head of crime, Detective Chief Superintendent Andy Cox, said: “This has been a tragic, extraordinary, and worrying set of circumstances in equal measure.
“A woman and child have lost their lives in the most devastating way and I know their loved ones will be feeling the magnitude of that today and our thoughts go out to them.
“We have also seen communities in Louth, and indeed further afield, who will undoubtedly have been anxious about the possible danger in the town since last night.
“To all of you, I want to say thank you. You have been listening to our safety advice and sharing our appeals, all of which has helped us to do our job to the best of our ability.”
