Police are searching for Connor Phillips, who is missing from St Leonards.
The 18-year-old was last seen at his address around 10am on Wednesday 20 November and officers are appealing for anyone who sees him to get in touch.
He left his house on foot and is not in possession of a mobile phone.
Connor is described as white, 5’9” to 5’10”, of slim build, with dark brown short hair. He was last seen wearing a camouflage army style branded ‘Stone Island’ jacket with a fluffy hood, black tracksuit bottoms and white Nike Air Max 97 trainers.
He is known to frequent the Falaise Skate Park area, Source skate park, Alexandra Park and Glyne Gap, including Ravenside.
His bike has been left at home, so he will likely still be on foot.
Anyone who sees him is asked to report it online or call 101, or 999 in an emergency, quoting serial 347 of 20/11.
