On Saturday, police finished a second round of interrogation, for six days, with the Toronto University student and produced him in court where Dhaka Metropolitan Magistrate Delwar Hossain ordered him sent to jail.
Rana Kumar Bhakta, general recording officer of the court, said Tahmid's lawyer Hamidur Rahman applied for his bail which the court rejected.
Police did not ask for further remand.
Another survivor of the attack, former North South University teacher Hasnat Reza Karim, was arrested along with Tahmid on August 3 night under section 54.
Both were placed in court and taken for eight days of interrogation starting August 4.
After the eight-day remand Hasnat Karim was shown arrested in the Gulshan attack case, becoming the first person to be accused in the terrorist attack. He was sent for more interrogation.
Tahmid was also placed on six-day remand, but he has not been shown arrested in the case.
