The Criminal Investigation Department (CID) of police arrested the gang, including its leader Jashim Uddin Bhuiyan alias Munnu.

Among them, Muhaiminul and Sanwar were involved in leaking question papers of Dhaka University. They were arrested from the capital's Mirpur on 19 and 20 July.
The duo on Wednesday gave confessional statements in the court.
The court put the rest of the three on seven day remand.
The CID also seized saving certificates worth Tk 22.7 million, cheques of Tk 23 million from Jashim and cheques worth Tk 8.4 million from Parvez.
According to CID, they amassed huge amount of money from selling question papers to admission seekers.
CID made the disclosure at a press briefing on Thursday afternoon at its headquarters in the capital's Malibagh.
Suman Kumar Das, senior assistant superintendent of CID’s cyber crime unit, told journalists that they had come to know about the organised gang from some accused arrested earlier over an incident of question paper leak of Dhaka University.
Back in 2017, CID investigated the incident of question paper leak of Dhaka University’s admission test.
Later, a case was filed in this connection and 125 people were charged in the case.
Among the 47 arrested in that case, 46 gave confessional statements before the court.
Suman said some of the accused had revealed the name of the gang during their statement.
On 19 July, the CID arrested Sanwar. Four others were caught later.
A case has been filed with Mirpur police station in this connection accusing 14 named persons including the arrested five and 150-200 unnamed people.
CID official Suman said question papers of the medical and dental admission tests had been leaked repeatedly from the press under the Directorate General of Health Services (DGHS).
DGHS has been printing the question papers since 1988.
The press’ machine man Salam and his cousin Jashim established a network around the country and were selling question papers over the years, said Suman.
CID officials said the gang used to sell a question paper for Tk 500,000.
Asked if any DGHS official was involved with the gang, CID officer Kamrul Ahsan said everything will be clear in interrogation.
