A US man who allegedly tried to kill his son with a chainsaw has had his leg amputated after being run over by a lawnmower.

Douglas Ferguson, from Tennessee, was found bleeding from his leg and head after police were called to an address on 28 June, Sullivan County sheriff's office said.

The 76-year-old had allegedly tried to launch an attack with a chainsaw while his son was cutting the grass, according to a preliminary police investigation.

Detectives say the father and son had an ongoing feud.

Ferguson has been charged with attempted second degree murder and violating probation.


An arrest warrant had to be delayed because of the severity of his injuries, local media reported.
