A man has been arrested over the death of an elderly man who died in a hit-and-run crash in Somerset.
The 38-year-old, from the London area, was detained after David Hick, aged in his 80s, died more than a week after he was found with head injuries in Cole Road, Bruton.
Police have also traced a black Chrysler Grand Voyager believed to have been involved in the incident.
A man and woman who were arrested were released earlier this week.
Mr Hick, a retired engineer, was walking to a local shop with his two dogs when he was struck by the car.
