Officers searching for missing Daniel are releasing photos of his distinctive tattoo alongside the trainers he is thought to be wearing and the bag he is believed to be carrying.
Thirty-year-old Daniel was last seen in Watford town centre at around 8am on Wednesday (3 January).
Daniel, who is from Watford, is described as 5ft 6in tall and of medium build, with black hair and a beard. Officers have been carrying out extensive enquiries to trace him and are now releasing a photo of a distinctive tattoo that he has behind his right ear.
Images are also being released of the same white trainers he is believed to be wearing and the black holdall bag he is thought to be carrying.
Police teams have been out searching in key locations, including Whippendell Woods, West Herts Golf Club, Cassiobury Park and the areas surrounding The Grove Hotel.
Detective Inspector Chris Parperi, from the Watford Local Crime Unit, said: “We are growing increasingly concerned for Daniel’s welfare and are doing everything we can to trace him.
“I am asking the public to please take a look at these photos and get in touch if you think you have seen Daniel.
“I would also like to thank the public for all their help so far. Please continue reporting any sightings to us. We politely ask that members of the public refrain from conducting any searches themselves as these could impede our work to find Daniel. However, you can still do your bit to help by continuing to keep an eye out, reporting sightings, and sharing our appeals on social media.
“If you have information that could help, please report it via the non-emergency number 101. For immediate sightings, call 999 straight away.”
