Six police officers dismissed from the force for helping Praween “Kamnan Nok” Chankhlai escape arrest following the fatal shooting of a policeman at his house have been moved to the Bangkok Remand Prison.

The six officers were dismissed from the force over their alleged involvement in the aftermath of the fatal shooting at a dinner party at the house of Mr Praween, then a kamnan in Nakhon Pathom, early this month. They were accused of helping the suspected gunman and Mr Praween to escape.

Mr Praween, 35, is also being detained at the Bangkok Remand Prison. He is a prime suspect in the murder of Pol Maj Sivakorn Saibua, a highway police officer, on the night of Sept 6. About 30 policemen reportedly attended the event.

According to earlier reports, Pol Maj Sivakorn had rejected Mr Praween’s request for the promotion of his nephew, a highway policeman. Gunman Thananchai Manmak, an associate of Mr Praween, subsequently fired multiple shots from close range at Pol Maj Sivakorn. He died and some stray bullets injured Pol Lt Col Wasin Panpee of Highway Police Sub-division 2.

The gunman was killed two days later in an exchange of fire with police in Kanchanaburi, and Mr Praween surrendered to police.

The Bangkok Remand Prison has eight zones but the six officers will be held in a different zone from Mr Praween, said a source familiar with the case.
