The prosecution yesterday completed its closing arguments in the much-talked-about August 21 grenade attack cases. 

After completing his arguments, Syed Rezaur Rahman, chief prosecutor of the cases, appealed to the court to award highest punishment to the offenders involved.

He also submitted two petitions to the court praying to cancel the bail of eight accused, including three inspector generals of police Ashraful Huda, Shahudul Haque and Khoda Baksh Chowdhury, and send them to jail.

The lawyer said the grenade attack on the Awami League rally on Bangabandhu Avenue on August 21 of 2004 was pre-planned.

He further said none of the accused was implicated in the cases politically, adding that they were brought under trial on specific charges.

At least 24 people were killed and around 300 injured in the grisly attack.
