A London man has been arrested in Devon on suspicion of attempted murder.
The man was stopped in his vehicle and arrested by police at the Westpoint layby in Exeter on Thursday morning.
Police arrested him after another man, 41, suffered serious head and facial injuries in Newton Abbot on Wednesday night.
The victim is currently in Derriford Hospital where he has undergone surgery. He is in a serious but stable condition, police said.
Anyone with any information is urged to contact the police.
