A migrant worker from West Bengal, who was pushed into Bangladesh by security agencies, has been booked for “illegally entering” the neighbouring country, State’s Migrant Welfare Board chief Samirul Islam said on Tuesday.

Mr. Islam, who is also a Trinamool Congress MP, was referring to the detention and “pushback” of Amir Sheikh from Kaliachak. He was picked up from Rajasthan in May this year and sent to Bangladesh.
