Tayeng (70), who represented Dambuk Assembly constituency in Arunachal Pradesh passed way last night and is survived by his wife, three sons and a daughter, family sources said.
Chief Minister Nabam Tuki expressed shock and grief over the death of Tayeng.
"Jomin Tayeng has left a void that would be difficult to fill in near future. He was not only an able administrator all through his life as a top bureaucrat but also a perfect people's representative after his retirement," Tuki said in a smessage.
