CHN is a legislator and CN is a businessmen, he added.
"At Widya Chandra, the investigators seized Singaporean dollars estimated worth Rp2 billion to Rp3 billion. The money was believed to be offered by CHN and CN to AM allegedly in connection with the regional head elections in Gunung Mas District, Central Kalimantan.

They are now being detained for questioning for 1X24 hours, Budi said.
