Police have released an image of a missing man in a bid to track him down after fears were raised over his welfare.

Jon Hannon, from the Harwich area, was last seen by a friend in the town at around 8.30am today.

Officers are concerned for the welfare of the 25-year-old, an Essex Police spokesman said, and are asking for help from the public in tracing him.

He is a white man, quite sun-tanned, with mousey brown short spikey hair which is shaved at the sides.

He is 5ft 9ins tall and was last seen wearing a green T-shirt with a target on the front, knee-length camouflage shorts, and may have a blue rucksack with him.

Call police on 101 to help.
