In Malaysian prison cell, the police officials kept me in a dark room alone, claimed Rayhan Kabir  after  return to home on Friday midnight.

He said it while talking with the BBC Bangla on Saturday.

Rayhan said, after detention, the different agencies' officials interrogated me for several time. They put pressure on me for changing my statements, but I did not agree.

"More than 14 agencies interrogated me at the detention time of mine."
I was asked if I had any political affiliation, how I came in touch with Al Jazeera, if I was paid to criticize the government, and if I had any person or organization behind me.

I thought they wanted me to make a statement through someone I interviewed. "
However, Raihan Kabir said that he never changed his own statement.
"I have personally spoken to Al Jazeera about the plight of the workers there. I have repeatedly told them that I had not spoken out against the Malaysian government. As a normal person, I have spoken out about the irregularities."

Although he was not abused while in police custody, he was kept alone in a dark room, said Raihan Kabir.
He also said that Bangladesh embassy officials met him several times during his detention.

After three weeks in  detention , Mohammad Rayhan Kabir return ed to Bangladesh by a Malaysia Airlines flight MH196.  The plane landed  at Hazrat Shahjalal International Airport around 12:55am on Saturday.
On July 3, Al Jazeera published an investigative documentary. 

It raised the issue of the government's repressive treatment of migrant workers in Malaysia during the lockdown. In the documentary, along with the citizens of many other countries, Rayhan also gave an interview, which angered the Malaysian authorities.

A warrant was issued against Rayhan Kabir. He was arrested by Malaysian police on the evening of July 24. After 14 days of interrogation, the police produced him in court on August 8. The court granted a 13-day remand if the police wanted a 14-day remand. After the remand ended on Wednesday, police said there were no charges against him.

Immigration police then decided to send him back to Bangladesh.
Rayhan was informed on Friday morning that he would be sent back to the country at night. Earlier, his luggage and other necessary items were brought there and his ticket was confirmed.

Before arrest, Rayhan Kabir sent a WhatsApp message where he said, "I did not commit any crime. I did not lie. I have only talked about discrimination against the migrants. I want the dignity of migrants and my country ensured. I believe all migrants and Bangladesh will stand with me".

Even during interrogation, Rayhan told the Immigration Police that he spoke about what he had seen and that was his own observation. But he did not want to hurt Malaysians.

Different international and Bangladeshi organisations, including Human Rights Watch and Amnesty International, have condemned the arrest and demanded Rayhan's immediate release.

Rayhan Kabir's family lives in Bandar upazila of Narayanganj. Locals said he used to help students with his books and financially, and was very vocal against drugs in the area.
