Both the Office of the Narcotics Control Board (ONCB) and police confirmed on Friday the likely link between murder suspect Priyanuch Wangnonchai and the illicit drug trade.

Police said, however, that the link has nothing to do with the murder, which was apparently carried out over vengeance.

“After we talked to the ONCB, we found that there is grounds to believe she is involved in drugs,” Deputy National Police Commissioner Pol General Chalermkiat Srivorakan said.

Chalermkiat met with ONCB secretary general Sirinya Sittichai on Friday.

Sirinya refused to reveal the details of how Priyanuch had been involved in drug-trafficking gang because it might affect the ongoing investigation.

“We have now worked with Myanmar police in gathering evidence. When we get more evidence, we will press drug charges against her,” he said.
