A couple in China were found sleeping on a bed, stacked up with bank notes totaling more than 80mil yuan (RM39.34mil).
Henan police made the discovery after arresting Li Wuzhi and his wife, Cui Yanyun.
The couple were accused of leading a group specialising in producing and selling drugs, following the seizure of 2.8-ton of mephedrone from them.
Also arrested were six other suspects, mostly family members and relatives of the couple.
