The accused are Shahadat Hossain Liton alias 'Khora' Liton, 35, Shamsunnahar Sheuli, 29, Al Mamun alias Mamun, 26, Abu Syed, 30, and Farhad Alam Hira, 24.

Of them, Hira is still at large while the rest others are now in jail custody.

The four accused -- 'Khora' Liton, Sheuli, Mamun and Abu Syed -- pleaded not guilty and sought justice before the court after Judge Momin Ullah of the Metropolitan Sessions Judge's Court read out the charges to them. Charges were framed against Hira in absentia.

The mutilated body of Turya, son of a jewellery trader in the city, was recovered from beneath the earth at Rampura on December 11, after 43 days of his abduction.

Police arrested Qayyum, Tajul Islam, Hiralal Ghosh, Khawza Azim and Farhad Alam but they were released on bail on different dates.

During the investigation, four of the accused gave confessional statements to the magistrate admitting their guilt.

The judge fixed May 22 for trial of the case and summoned complainant and other witnesses to appear before the court on the scheduled date.
