Murder squad detectives have arrested a 21-year-old man after an ex-Royal Navy officer was run over by his own car by burglars, as a neighbour said the victim's wife screamed his name and called for help as he lay dying in the street.

Mike Samwell, 35, confronted intruders who broke into his home as he slept upstairs with his wife, Jessica, at about 3am on Sunday.

He was found badly injured in a parking area at the rear of the house in the Chorlton-cum-Hardy area of south Manchester and died little more than an hour later in hospital after being run over by his black Audi S3.

Reports on Monday said his wife, an accountant, had witnessed the incident in which her husband was killed.
