A 91-year-old man was hurt in a carjacking as he parked his car outside his own house.
The pensioner was pulled from his blue Renault Clio in Shotton Colliery, County Durham, by one man before two others jumped in and drove off.
He suffered a cut to one of his arms during the Friday night attack and was treated by paramedics at the scene.
Two men in their mid-20s and one aged 19 have been arrested in connection with the robbery.
Detective Chief Inspector Aelfwynn Sampson, of Durham Constabulary, said: "This was a callous crime carried out on a vulnerable elderly man whose car is his lifeline.
"I would urge anyone who can help with our investigation to contact us."
