Imphal: A mob attacked a convoy of Manipur Police at Longja village in the state’s Chandel district, damaging several vehicles, though no injuries were reported, officials said on Thursday. One of those vehicles belonged to the Additional Superintendent of Police of the Chandel district, which shares an unfenced border with Myanmar. In a separate operation, security forces have arrested a self-styled corporal of the People’s Liberation Army (PLA) militant outfit. He said that the security forces have provided escorts to a large number of vehicles carrying essential items along Imphal-Jiribam National Highway (NH-37). The police also appealed to people to return the looted arms, ammunition and explosives to the police or the nearest security forces post immediately.
