Violence erupted on the last day of nomination filing for the April nine assembly elections in the state, when supporters of a candidate vandalised the office over a petty issue, election office sources said here.
DGP Satyendra Garg could not elaborate on the incident as he could not establish contact with the district SP due to poor telecom connectivity.
No one was injured, the sources said.
Chief Electoral Officer Chandra Bhusan Kumar said a company of security forces was dispatched to Koloriang from nearby Ziro in Lower Subansiri district to restore oder.
The election observer for Kurung Kumey district R N Lal who was to go by road during the day would fly by helicopter to Koloriang tomorrow accompanied by Garg and Home Commissioner to assess the situation, the sources added.
