Talking to The Daily Star after yesterday's programme, Tutul said one of his family members filed a general diary with Khilgaon Police Station on the day his son Tasin died. He said they wanted to file a case, but police told him that they would file it themselves.
"A few days after the death of my son, I called the investigation officer of the case to know about the progress. He told me that they could not arrest the bus driver. Besides, the vehicle was handed to its owner," he said.
In the last one year, Tutul, with help from different organisations, organised seven human chains and press conferences seeking justice for his son.
He said he wrote to the prime minister, the Inspector General of Police and the commissioner of the Dhaka Metropolitan Police. He also met the mayor of Dhaka North City Corporation thrice, he said.
"I suffered a paralysis in 2017 but now I am recovering. With my poor health, I knocked almost all the doors but perhaps have failed to do anything for my son," he said.
Contacted, Ripon Kumar, the newly-appointed investigation officer, said police had filed a case in connection with the accident.
Last month, the law enforcers submitted the charge sheet to the court against the bus driver, he said, adding that the accused was, however, on the run.
