Two persons suspected to be Rohingya refugees have been arrested by the Uttar Pradesh Anti Terrorist Squad (ATS) in Ballia for allegedly staying in the country illegally, an officer said on Wednesday.

The Varanasi unit of the ATS and the Ballia district police arrested the duo -- identified as Arman alias Abu Talha and Abdul Amin -- based on a tip-off. After his arrest, Arman told the police that he is a Rohingya refugee and had come to India in 2008, the officer said.
