There is an uneasy feeling on the streets of Bangkok, a week after a bomb killed 20 people at one of the city’s most visited shrines.
Other countries use biometric systems like finger print, facial and iris recognition
Officers say the trail has gone cold.
The only evidence police have to go on is security camera footage from the scene. It is thought to show the suspected bomber slipping off a backpack before walking away.
A computer image of the suspect wearing a yellow t-shirt and with black hair has been published.
He was seen leaving on the back of a motorcycle taxi. After that, there is no trace.
Lack of modern technology?
The chief of police says a lack of modern forensic technology is hampering the search.“Other countries use biometric systems like finger print, facial and iris recognition. Thailand does not possess this technology yet.” Thai police chief Somyot Poompanmuang told reporters at a press conference.
A suspect device was detonated safely at a building site on Sunday.
Thai tourism – also a victim?
The government thinks last week’s attack was aimed at undermining the economy by hurting tourism.
The Erawan Shrine to a Hindu deity is popular with Asian sightseers. Half of the foreigners killed were from mainland China or Hong Kong – Thailand’s biggest source of tourists.
