POLICE officers have issued an appeal after growing increasingly concerned for the welfare of a teenager who has not been seen for at least five days. 

Nathan Frost, 17, was reported missing from Southchurch Avenue, in Southend, on Monday.

He is described as being white, 5ft 9ins tall, and slim, with cropped, curly, light brown hair and a beard.

Nathan was last seen wearing navy-coloured tracksuit trousers, a black and white Adidas t-shirt, white trainers with a Burberry print, and a dark-coloured rucksack.

After exhausting all lines of enquiry available to them, officers are now asking for help from members of the public. 

A spokesman for Essex Police said: "We’re concerned for Nathan's welfare and need to find him to make sure he’s ok.

"We need anyone who saw him or has any information about where he is to get in contact."
