A new image has been released of a man who has been missing over a week.

The search for Viktor Vaimel, who was last seen in Rickmansworth last Saturday (July 3) at around 10am, continues after extensive searches.

Dive teams were deployed at the River Chess on Thursday for the 41-year-old, as police state they are increasingly concerned and consider him to be vulnerable.

Viktor is described as 5ft 10in tall with short brown hair and blue eyes. He is believed to have been wearing blue jeans with a white T-shirt, white trainers and a black jacket. Police say he is a smoker.

According to Hertfordshire Constabulary, while he was last seen in Rickmansworth he may also be in the Croxley Green area, while he also has links to Tottenham and often travels by train.

Today’s appeal is the fourth one since his disappearance was first made public last Sunday.

The new picture is hoped to help people identify Viktor.

Anyone who spots Viktor is asked to call 999 straight away, whereas anyone with information on his whereabouts can call 101 quoting ISR 421 of 3 July.
