A team of police of the Special Branch (SB) and Immigration led by Special Superintendent (Immigration) Shah Alam launched the drive at around 7:00pm in connection with a case filed with Airport Police Station on November 17 after the immigration police rounded up 31 women workers who were about to fly to Lebanon with fake documents.

The seized documents include composed copies of emigration clearance certificates and a number of formats for medical certificates, which were prepared by the agency illegally, said Shah Alam.

The officials also could not provide any satisfactory answers with regard to the passports and documents, he told reporters.

Many passports also do not have the security features, which are mandatory for the passports to be genuine, he added.

More than 200 passports were marked with departure seals, but no marks of arrival seals were found in those passports, which proves that the passport holders dodged the immigration police in the airport, he added.

Such agencies extort the workers both at home and abroad, Shah Alam said, adding that the amount they realise from each worker is much greater than that fixed by the government and they also collect money from the workers in the foreign lands before their deportation.

The police also showed a number of papers on agreement between the aspirant migrant workers and the agency, which states that the agency cannot be held responsible if the workers fail to go abroad for any reasons. In such cases, the workers will also not get back the money they paid to the agency, the paper reads.

Meanwhile, the Ministry of Expatriates' Welfare and Overseas Employment suspended the four officials of Bureau of Manpower, Employment and Training (BMET) who were detained by the police following the November 17 incident.

BMET Director (immigration) Manjur Rahman was also made OSD (official on special duty) for his alleged involvement in issuing emigration clearance certificates to the 31 women.

A committee led by the BMET additional director general was formed on November 19 to investigate the case. The committee is expected to submit its report in three days, according to an official handout.
