The Metropolitan Police has offered a £10,000 reward for information about a teenager who disappeared from north London nearly 17 years ago.
Accountancy student Alexander Sloley was just 16 when he vanished in August 2008, two days before his birthday.
Despite extensive investigations spanning almost two decades, police have found no trace of the teenager.
His family and friends have not heard from him since he went missing from Islington, while his case remains an active missing person investigation.
