The search for a missing teenager from Hatfield is continuing almost three weeks after he was last seen.
17-year-old Nathaniel was last seen at around 6pm on September 15 at his home address.
He is described as being between 5ft 7ins and 6ft tall, of slim build, with short brown hair.
He was last seen wearing off-white-coloured joggers and a long-sleeved off-white sweatshirt. He was also carrying a bag.
He also has links to Hatfield, Barnet in London and Stoke-on-Trent in Staffordshire.
Police appealed last week to find Nathaniel, but he is still missing and concern is growing for his welfare.
If you have any information about where Nathanial has been, call the non-emergency telephone number 101.
If you believe you are with him now or have seen him in the last few moments, call 999 immediately, quoting ISR 24 of 17 September.
