The announcement was posted on the GLO’s website on Thursday night.
It warned that legal action would be taken against any people who found the package and did not return it to the GLO. The disappearance of the tickets had been reported to police, and the numbers cancelled.
The package containing the tickets was addressed to the governor of Ayutthaya province.
Meanwhile, the National Council for Peace and Order (NCPO) will tackle the root cause of overpriced lottery tickets by focusing on wholesalers and agents who reap the profits from inflated ticket prices.
NCPO chief Prayuth Chan-ocha yesterday assigned Gen Vichit Sriprasert to meet state agencies to discuss the overpricing problem and work out solutions.
Gen Vichit said the council would tackle the problem once and for all. It would look for ways to deal with those profiteering from the overpricing of tickets.
A pair of tickets now sells for 100-110 baht, and more for favoured numbers. The face value is 80 baht, or 40 baht a ticket.
