Sources said Naga organizations had earlier this week submitted a memorandum to the Union Home Minister requesting him to deport illegal Myanmar immigrants.

The memorandum said that around 5,457 illegal immigrants from Myanmar are being given shelter in eight Tangkhul villages in Kamjong district of Manipur, bordering Myanmar and they outnumber the local residents.

Having recently visited the India-Myanmar border areas on a fact-finding mission, the United Naga Council (UNC), Naga Women's Union (NWU), All Naga Students Association Manipur (ANSAM) and Naga People's Movement for Human Rights ( NPM-HR) ) Memorandum submitted to the Union Home Minister.

A UNC leader said that a section of migrants are involved in illegal and anti-social activities and law enforcement agencies are unable to control such activities effectively.

"Though biometrics of 5,173 persons have been taken, monitoring the movements of adult male prisoners (illegal immigrants) has become a major challenge as the authorities deal with the fluctuating number of prisoners between day and night in those temporary refugee camps. Cannot practice verification regularly." the UNC leader said, declining to be named.

A Manipur home department official said the state government, in coordination with the Ministry of External Affairs and central security forces, has deported 115 Myanmar nationals, including women and children, in three phases from March 8.

Immigrants from Myanmar have been deported through Moreh border in Tengnoupal district of Manipur.

Manipur has an approximately 400 km long unfenced border with Myanmar.

Manipur Chief Minister N Biren Singh had earlier said that although India is not a signatory to the 1951 Refugee Convention, it has provided shelter and assistance to those fleeing the crisis in Myanmar on humanitarian grounds.Since the army took over Myanmar more than three years ago, at least 8,000 Myanmarese have taken refuge in Tengnoupal, Chandel, Churachandpur and Kamjong districts of Manipur, while more than 36,000 have taken refuge in Mizoram.

Following the advice of the Ministry of Home Affairs (MHA), the Manipur government is collecting biometric details of Myanmar nationals taking refuge in the state.

However, the Mizoram government had initially turned down the Home Ministry's appeal to collect biometric data of Myanmar refugees. However, recently the state government decided to collect biometric details of refugees.
