KUALA LUMPUR: A Pakistani and two Malaysians have been detained in connection with last month's bombing of a shrine in Bangkok that killed 20 people, the national police chief said Monday.

Inspector General Khalid Abu Bakar told reporters that the three were detained a few days ago following a tip-off by Thai authorities. He said one of the Malaysians is a woman.

The August 17 blast at the Erawan Shrine in the Thai capital killed 20 people, including five Malaysians from one family, and injured more than 120.

Many of the victims were foreigners as the shrine is a popular destination for tourists and Thais alike. Khalid did not give details or say where in Malaysia the three were detained, when they will be formally charged, or what the charges would be.

He said Malaysian police will investigate and work with Thai authorities on the detainees. Thai police say the man who may have actually planted the bomb may have fled across Thailand's southern border to Malaysia, but Khalid refused to speculate on that.

In Bangkok, Thai Police Chief Somyot Poompanmoung said he has not received any information from the Malaysian police on the arrest of the three suspects.
