Criminal Investigation Department (CID) arrested a machine operator of Directorate General of Health Education (DGHE) on charges of leaking medical and dental admission test question papers.
A team of CID's cyber police unit arrested Abdus Salam from the capital's Banasree area on Monday, Special Superintendent of CID Ashraful Alam told reporters at a briefing at its headquarters.
Salam, "one of the masterminds of a question-leak gang", went into hiding after CID arrested five members of the group on July 19, he said.
After arresting the five, CID said the question papers of medical and dental admission tests were leaked repeatedly from the printing press under DGHE.
According to CID, Salam used to leak questions from the press for many years, with help from influential department officials. Another accused, Jasim -- who was arrested during the July 19 drive -- used to spread the leaked questions all over the country using a strong network.
Through this, they embezzled crores, CID officials said, adding that hundreds of students got enrolled into medical and dental colleges through this gang.
The officials said they came to know through multiple sources that these question papers were printed from the press under Directorate General of Health Services (DGHS) since 1988, and members of this ring were somehow linked to the printing press. DGHE, previously a bureau under DGHS, continued employing the same printing press after it was formed as a separate body.
CID said the accused used to supply the papers digitally before exams between 2013 and 2018, in exchange for hefty amounts of money.
They found at least 50 people in the racket across the country.
In 2015, medical tests were marred with allegations of question leaks, followed by weeks of protests demanding retakes. However, no action was taken.
The racket came to the spotlight while CID was investigating question leaks at Dhaka University's admission test in 2017, and found another ring in 2018.
