He made the statement while talking to journalists at a programme held at Bogra Shaheed Titu Auditorium Wednesday morning.
He said: “Many families have contacted us regarding the surrender. We will make the information public after talking needful measures.”
The RAB DG said a total of 24 suspected militants had been detained after the attack in Gulshan’s Holey Artisan Bakery on July 1. Of them, two were killed in gunfights while the rest were produced in courts.
Earlier in the day, two militants surrendered to the elite force in the programme.
He said RAB will rehabilitate the two militants.
Wishing anonymity, a RAB official said: "We will ensure their [two militants] security. They have been given the money to help start their career."
Home Minister Asaduzzaman Khan Kamal said: “We could have destroyed the militants but Prime Minister Sheikh Hasina has asked us to give them a chance to come back to their families and rehabilitate. If they do not surrender then they will be caught.
“We know who their leaders are. We are trying to trace them out.”
Regarding Durga Puja, he said: “The people of Bangladesh are religious, not fanatic. They celebrate every festival together.”
Kamal said around 2,975 Puja pavilions have been set up across Bangladesh last year which has spiralled up to almost 3,000 this year.
