Police have issued a renewed appeal for information regarding the whereabouts of 50-year-old Mark Dinsmore from Bushmills, who has been missing since a road traffic collision last month.

Mr Dinsmore was last seen at approximately 6pm on Saturday, 24 October, when his grey Audi A4 was involved in a collision with a grey Nissan Juke on the Ballybogey Road area of Ballymoney. He has not been in contact with family or friends since, and police believe he sustained injuries during the incident. There are serious concerns for his welfare.

He is described as approximately 5ft 8in tall, of medium build, with short dark hair. At the time he was last seen, he was wearing a red coat, a white t-shirt, jeans, and white trainers.

On Saturday, 31 October, police returned to the Ballybogey Road to speak with passing drivers in the hope they may have been in the area the previous week. Inspector Armour said those spoken to were keen to help with enquiries.

Police have asked anyone who was travelling along the Ballybogey Road on the evening of 24 October and who came across the collision between Mr Dinsmore's vehicle and the grey Nissan Juke to contact them. They also continue to appeal for relevant dash-cam footage or any details relating to the collision or Mr Dinsmore's whereabouts.

Inspector Armour said every piece of information, no matter how insignificant it may seem, could help. He also thanked everyone who has assisted so far, noting that police continue to work alongside voluntary search and rescue partners, and that members of the public have helped by checking outbuildings, sheds, and unoccupied buildings. Mr Dinsmore's family are said to be appreciative of every person who has come to their aid.

Anyone with information should contact police on 101, quoting reference number 431 of 25/10/26.
