Police investing last month's Bangkok bomb blasts want to interrogate a taxi driver who regularly drove some of the main suspects.
Royal Thai Police spokesman Lt-General Prawut Thavornsiri yesterday said that the cab driver was found to have offered his service to some of the foreigners suspected of involvement in the bombs at the Erawan Shrine and Sathorn pier.
"We got new information that this taxi driver drove for the suspects regularly, particularly the man in the blue shirt who was involved with the explosion at Sathorn pier," Prawut said.
The spokesman said that police had allowed three people questioned as witnesses in this case to go home after being interrogated, adding that they had provided "useful information" to investigators.
Prawut said that the witnesses who had earlier been in military detention knew the suspects but they appeared to have no involvement with the attacks.
He added however that they would be charged later if they were found to had a role in the blasts.
The three witnesses were identified as Pakistani man Jawed Igbal, Panisara Chaleeratrom, the wife of a wanted Pakistani named Abdul Tawab, and taxi driver Chob Sakulthong.
Prawut said that based on the latest information obtained from the three witnesses, police had been able to make a sketch of the man in blue shirt, who was caught on a security camera dropping an explosive device into the water at Sathorn Pier.
He said that police would disclose the information later.
