The five shot and hacked to death 20 foreign hostages at the Holey Artisan Bakery on July 1 in Dhaka's Gulshan neighbourhood -- an attack claimed by the self-styled ISIS.
Military commandos brought the hostage crisis to a bloody end the next morning after they stormed the compound and gunned down the extremists.
The military handed over the bodies of the five attackers and their alleged associate to the police today after no relatives came to claim the bodies for nearly three months.
"We gave the six bodies to Dhaka Metropolitan Police. Since their death no one came to us to take the bodies," military spokesman Colonel Rashidul Hasan told AFP.
Dhaka police spokesman Masudur Rahman said they handed over the bodies to the Anjuman-e-Mufidul Islam, a Muslim charity which collects and buries unidentified bodies according to their religious rites.
The father of one of the attackers told AFP he had disowned his son after he learnt about the attack. He said he was too "ashamed" to be the father of an extremist.
Local media reported that other families were reluctant to take the bodies as they did not want to be seen as sympathic towards their children.
Since the attack Bangladeshi security forces have shot dead at least 28 suspected Islamist extremists in a massive crackdown.
Police have said a local Islamist extremist outfit, led by a Canadian citizen of Bangladesh origin, was responsible for the cafe carnage, rejecting ISIS's claim that its fighters carried out the attack.
