Police in Belgium have offered a reward of two million euros (£1.36m; $2.5m) as they hunt a thief who stole diamonds worth $28m (£19m) from a bank.
The bank is in the heart of Antwerp's famous diamond district
The gems were taken from the vault at a branch of the Dutch bank ABN Ambro in the city of Antwerp, where half the world's diamonds are traded.
A composite picture of the suspect has been issued by police.
They said he was a regular customer at the bank and appeared to have prepared for the theft for over a year.
The robbery was discovered a week ago, but has only now been made public.
Several safes were broken into and the haul included both cut and rough diamonds, police said.
