A suspect has been arrested in Bangkok in connection with the bombing that killed 20 people in Thailand's capital 12 days ago.
The man is thought to be a 28-year-old Turkish national, a police spokesman has said.
When officers raided his flat in a northern Bangkok suburb they found materials including detonators and metal pipes for making bombs, which police said were the same type as those used in the bombing of the Erawan shrine.
They also found dozens of passports, one with his photo.
A Thai TV station apologises after dressing up a member of staff as the Bangkok bombing suspect and sending him to the scene of the blast.
