The former chairman of Samsenwittayalai School's alumni association gave the National Anti-Corruption Commission (NACC) additional information Wednesday in connection to an alleged "tea money" scandal at the school.
Chana Wongmusik said he was heartened to see both the NACC and Education Ministry probing the case, adding there were rumours the graft-busting agency had obtained fresh information from some of the students' parents.
Mr Chana did not say what additional information he presented to the NACC, which will meet the Education Ministry to discuss the matter on March 14.
He said he expects the ministry to wrap up its probe and decide on punitive measures this month.
The school made headlines last June after a parent circulated a video clip showing a man -- allegedly school director Viroj Samruan -- demanding 400,000 baht in "tea money", a euphemism for a bribe, from a parent in exchange for enrolling his child in Mathayom 1 (grade seven) at the school.
The parent allegedly recorded every contact with the school director, including phone calls and the handover of the purported bribe. The director was said to have had his deputy accept the cash on his behalf.
Mr Viroj insisted he never took the money and was being blackmailed by a group of school alumni who were upset because some of their children could not get into the school.
He also claimed the video showing the payment had been doctored to defame him.
Mr Chana said Wednesday he asked the NACC to conduct a further check to see if other Mathayom 1 and Mathayom 4 students who were admitted into the school last year were properly enrolled. He denies talk of a blackmail plot.
State schools are required by law to accept students wholly on the merit of exam results. It is unclear what fate awaits Mr Viroj.
