Alima Bibi along with Rajira Bibi were arrested from Khargragarh in Burdwan for being allegedly involved in the blasts on October 2 last year.
"Alima Bibi has delivered a baby boy in hospital few months back. She was taken to a hospital as the jail hospital doesn't have facilities to deliver child. She is now being given special diet as per court ruling in case of inmates who give birth. Both the baby and Alima are doing fine," said a senior official of state correctional home department.
The October 2, last year, an accidental blast took place while manufacturing IEDs in Burdwan's Khagragarh area led to the arrest of three terror suspects who are members of terror outfit Jamaat-ul-Mujahideen Bangladesh (JMB).
The police recovered bodies of two JMB members - Shakil Ahmed and Sovan Mandal -- and arrested Amina Bibi and Rajira Bibi.
The probe into the blast was handed over to NIA and several more terror suspects were arrested.
