They also urged the government to make public the allegation on which Jalil was arrested.

In a statement, Jatiya Samajtantrik Dal (JSD) President Hasnaul Haque Inu and General Secretary Syed Jafar Sajjad said before arresting a national leader like Jalil the authorities should have filed a case and investigated specific allegation against him if there is any.

Expressing concern over the arrest, politburo of Workers Party said the arrest of Jalil has sent a wrong message about the political ambition of the government.

In a statement, they said the reason of his arrest has not been made public yet, which makes people think that Jalil was arrested due to his repeated reminders on preparing voter list and quick electoral reforms and lifting ban on indoor politics.

They also said people have welcomed government's anti-corruption drive but the attempt to make corruption and politics synonymous will not only hamper the anti-corruption drive but also create confusion and mistrust about the government's intention.

They demanded immediate release of Jalil to bring a healthy political environment in the country.

Bangladesh Awami Juba League President Advocate Jahangir Kabir Nanak and General Secretary Mirza Azam in a statement said the democratic process will be hampered if the government takes the 'political repression policy'.

The joint forces picked up Abdul Jalil from his Mercantile Bank office at Motijheel in the city at around 3:45pm on Monday.
