via Khmer Times, 20 December 2019: One villager returned a piece because he was reportedly haunted by spirits.
Villagers in Siem Reap province on Wednesday handed over two ancient pieces of pottery they had unearthed while clearing land for cultivation in 2011 and last year to Apsara Authority.
According to a statement issued on Wednesday, two villagers decided to hand the vases to the Apsara Authority because they felt that the items were possessed with spirits.
Nga Chanthou, chief of Run Ta Ek Eco village, said that he discovered an ancient vase in 2011 when his uncle was ploughing the field behind Banteay Srei temple in Banteay Srei district.
