Two top militants of the outlawed People's Liberation Army (PLA) of Manipur were arrested in the national capital, police said.
"We have arrested two high-ranking militants of the banned organisation," a senior police official said.
The PLA was formed in 1978 comprising of ethnic groups such as Nagas, Kukis and Meiteis with the objective of liberating Manipur. PLA militants are equipped with sophisticated arms and involved in extortion and killings.
In January this year, Delhi Police had arrested a 28-year-old self-styled Lieutanant -- Oinam Ibomcha Singh --of the banned outfit.
Singh had joined PLA in 1999-2000 and underwent training in handling of arms and ammunition in Myanmar in the camps of Maoists. His areas of operation were Delhi-Guwahati-Dimapur, police had then said.
