MANCHESTER: A man has been arrested on suspicion of murder after a former Royal Navy officer was killed by thieves who ran him over in his own car after he confronted them outside his home. Michael Samwell, 35, died after going to stop his black Audi S3 being taken in the early hours of Sunday in Chorlton-cum-Hardy, Manchester. Mr Samwell went down to investigate a “loud bang” that woke him and his wife, police said. He was found in the parking area behind his home with serious injuries and died a short time later in hospital. Greater Manchester Police said a 21-year-old man was detained in Chorlton on Monday morning. Earlier, they said Mr Samwell appeared to have been “run over by the vehicle, causing his injuries” as the thieves fled the scene in Cranbourne Road at 3am. A murder investigation has been launched. Detective Superintendent Jon Chadwick said: “My thoughts go out to Michael’s wife and his family, I cannot comprehend what they must be going through. “This is the murder of an innocent man who has merely sought to protect his property from criminals. “We will not stop until we have found the person responsible for this dreadful crime.” Mr Samwell’s car was found abandoned and badly damaged a short time later three miles away in Whitby Avenue in the Ladybarn area of the city.
