Detectives have arrested six youths on charge of extorting money from people introducing themselves as members of a top terror gang.
The cyber and special crime team of the Detective Branch of police arrested them from Jatrabari, Motijheel, Paltan and Turag areas in the city on Thursday.
Dhaka Metropolitan Police (DMP) Deputy Commissioner Walid Hossain revealed the information at a press briefing at the DMP media centre on Saturday.
He said the arrestees used to extort money from people, introducing themselves as members of "Seven-Star Group".
The arrestees are Billal Khan, Rakib Khan Titul, Abdul Hannan, Delwar Hossain, Md Sohag and Rashed Alam.
A case was filed with Jatrabari Police Station in this regard.
The DB's cyber and special crime team recently received a complaint from a victim. According to the complaint, a miscreant, claiming himself to be a listed top terror Jishan Mahmud, threatened the person over the phone demanding extortion.
"They work in three phases. One group collects the numbers of affluent persons and businessmen from phone directories and supplies the numbers to the second group. The second one makes calls to the targeted persons, claiming that several members of their gang are in jail and they need huge sums of money to secure their bail. That's why they are taking financial help from some established businessmen and important persons," said Walid.
The third group goes to the targeted persons' houses to collect the extortion money, he added.
Mentionable, the Seven-Star Group once was known for their notoriety, mainly in the capital. Top terrors like Subrata Bain, Mollah Masud and Murgi Milon were part of it.
DB officials said they conducted the raids based on a complaint of a Cox's Bazar-based businessman whom the gang called and demanded Tk5 lakh in extortion. He sent Tk35,000 through bKash, but they demanded more.
The gang also threatened the businessman to abduct and kill his family members, detectives said quoting the complaint they received.
