Bail of militant suspects remains a concern, reports The Daily Star on January 23. A database of Police Headquarters (PHQ) shows 4,881 people were arrested over their involvement with different militant outfits in 16 years since 2005. Of them, 2,456 walked out of jail on bail. A total of 251 suspects out of 2,456 went into hiding. Ariful Karim Chowdhury alias Adnan was arrested by Police in 2015 over his involvement with banned militant outfit Harkat-ul-Jihad-al Islami Bangladesh (HuJI-B). Coming out of jail on bail, he got involved with Ansarullah Bangla Team (ABT), another banned militant outfit, and started activities using online platforms. Soon, he became the ABT ‘chief’ of a part of Dhaka city and in-charge of fund collection. Rapid Action Battalion (RAB)arrested him again in the capital Dhaka city's Mirpur area on December 19, 2019. He has been behind bars since then. Samiun Rahman alias Ibn Hamdan is one of the top militants with experience of fighting for the Islamic State in Syria. Detectives of Dhaka Metropolitan Police (DMP) arrested him from Dhaka city on September 28, 2014. But he too managed to secure bail. He later collected an Indian passport illegally providing false information and fled the country. On September 17, 2017, New Delhi, India, Police arrested Samiun.
