RAB-3 Commander Lt Col Mohammad Emranul Hasan told bdnews24.com around 11pm on Wednesday that they quizzed the activist before his release.
Witnesses said Imran was about to join a scheduled protest rally against ‘extrajudicial killings’ in the ongoing crackdown on drugs in front of the National Museum at Shahbagh in the afternoon when the RAB whisked him away.
A Mancha activist told bdnews24.com around 11:30pm that Imran was heading home after being released.

“There are more charges against him. We are looking into the matter,” he said earlier.
The RAB also charged baton to disperse the protesters after the detention of Imran.
Police foiled a rally planned for Monday and said Ganajagaran Mancha had no permission to hold the protest programme.
Imran then announced the demonstration would take place at 4pm on Wednesday at the same venue.
The activists said they had completed all formalities for holding the rally.
Activist Sangeeta Imam said a human-chain demonstration by Bangladesh Chhatra Union against the ‘killings in the name of crackdown on drugs’ was under way at the same venue around 4:30pm.
Seven to eight plainclothesmen detained Imran when he was on his way to the venue with some other activists at the time, according to her.

“We wanted to protest as citizens of the state, but we could not do it. Even the UN is speaking against the so-called crossfires in the name of anti-drug operations, but we can’t do it as normal citizens. It’s a matter of shame for us,” she said.
Ganajgaran Mancha has called a news conference for Thursday morning to protest against the detention of Imran and attack on its activists. Chhatra Union has also demanded Imran’s release in a statement.
Shahbagh-based Ganajagaran Mancha came into being in 2013 when the protests demanding maximum punishment of war criminals peaked.
The ruling Awami League and its affiliates later started staying away from the movement.
They also brought allegations against Imran as the son-in-law of Education Minister Nurul Islam Nahid continued raising his voice against different other issues including rapes and killings.

Although the killings were portrayed as 'deaths in gun battles' by the law-enforcing agencies, human rights activists say these were extralegal killings.
“We support the campaign against drugs. But, no matter how big the culprits are, we should not kill any person without trial. So, we call upon the government to stop extrajudicial killings,” Imran had said after police foiled their rally on Monday.
“And now it appears from the government’s behaviour that Bangladesh is an autocracy. It seems the government is not accountable to the people,” he added.
