These CCTV images could hold vital clues to a raid on a Whitstable bank in which a cash box was seized from a security guard.

The G4S guard was carrying the box containing a sum of money outside Lloyds Bank at 10.30am on Wednesday was he was approached from behind and the cash box snatched.

He then fled in the direction of Middle Wall and Cornwallis Circle.

The raider was described as 6ft 2in, in his 30s and was wearing jeans, a high-visibility jacket and hard hat.

South East Coast Ambulance spokesman Richard Airey said paramedics treated a man in his 50s for shock.

Police are keen to speak to anyone who can identify the man in these pictures.
