PARLIAMENT The 12 police personnel nabbed following the discovery of mass graves in the Thai-Malaysian border in Wang Kelian, Perlis were released due to lack of evidence.

Four foreign nationals were charged with human trafficking offences, of which a Bangladeshi pleaded guilty, two Myanmarese were found guilty, while the trial against a Thai national is pending, Home Minister Ahmad Zahid Hamidi said.

"The 12 police officers suspected involved in smuggling migrant workers were arrested under the Anti-Trafficking in Persons and Anti-Smuggling of Migrants Act (Atipsom) and the Prevention of Crime Act (Poca).

"However, they have been released because there was insufficient evidence to convict them of the offence," Zahid said.
