A driver died when his car reversed and crashed into the wall of a building society in Buckinghamshire.
The 77-year-old, who is yet to be named and was the only person in the car, struck Nationwide in Radcliffe Street, Wolverton, Milton Keynes, on Friday.
He was taken to hospital, where he was pronounced dead. Police said the crash happened at very low speed, so the man may have suffered a "medical episode".
Officers want to hear from anyone who saw the black Kia C'eed at 1110 BST.
