Police are appealing for dashcam footage of the roads around West Suffolk Hospital in a bid to find a man who has been missing for more than two weeks.
Stephen Keyes, 52, was last seen at the Bury St Edmunds hospital on the evening of Monday, September 7 and was reported missing the following Thursday.
Mr Keyes, from Sudbury, is described as white, 5ft 6ins tall and with receding hair.
A CCTV image of him from the hospital shows that he was last seen wearing dark-coloured jeans and a dark-coloured jacket.
A spokesman for Suffolk police said officers are "extremely concerned" for Mr Keyes' welfare.
Police are now asking motorists who were driving in Hardwick Lane, Vinery Road, Sicklesmere Road or in the direction of Sudbury in Bury at about 9pm on the day of Mr Keyes' disappearance to contact them.
Anyone with information regarding Mr Keyes' whereabouts is asked to contact Suffolk police on 101.
