Cops on aware and already looking for them as of today. Some big boys from Bangkok are on their way to Pattaya to deal with this to make sure it's dealt with correctly and not paid off when the local police catch them.
The girl I know who they tried to shoot was helping the local police look through hours of CCTV in Pattaya to point out the van, which they were able to do. Now it's just a matter of finding who it belongs to and actually finding it parked or in route.
