Hundreds of military personnel and volunteers have been deployed in a search for a missing soldier.

Alex Cairnie, 30, a sergeant in the Queen's Royal Hussars regiment, was last seen at around noon on July 6 leaving Tidworth camp in Wiltshire.

Amesbury Police are now asking people to come forward if they have seen Alex, from Perham Down.

He is described as around 5ft 7ins tall, of an athletic build with mousy brown hair and a beard.

Military personnel have been deployed in the Tidworth area, working alongside specially trained volunteers and officers.

Police dogs have also been sent out, and a drone is using thermal imaging technology to check local woodland from above.

Amesbury Police stated: "We are very concerned for his welfare."

"He is thought to have been wearing a light coloured t-shirt and black/grey trousers."

"If you see him, or know of his whereabouts, please contact us on 999 quoting log 214 of today's date."

Among those joining the search as a volunteer is a team organised by Drew Short, from DS rescue and recovery.

He wrote: "We've got a search and rescue dog along with 3 trucks were more than happy to give up our time and money."

"We won't stop looking for you until you are found by someone. We're all really hoping you are ok and please reach out to someone."
