Were both pics taken at the same location? Looks like the pics were taken in different locations at different times to me and published in some article(s). Were they re-posted on somebody's FB page? The first pic shows a group possibly being hauled up for breaching a social distancing/curfew rule, with the whiskey bottle prominently displayed as "evidence". I think it was taken at Chang Puak police station in Chiang Mai.

The second pic shows a different group holding up the confessions they had signed - can't tell what for. Probably the same thing as breaching curfew/social distancing is the most common crime right now, especially among farang and Thai youngsters and one they want to make an example of.

The pics were recently taken as all of them were wearing masks. So can't be at any festival as all festivals have been banned since the emergency decree. I don't think they were taken in Surin at all.
