India's National Investigation Agency (NIA) on Thursday arrested at least eight people allegedly involved with last month's deadly bombing in the city of Hyderabad, according to The Indian Express.
The exact number of people taken in was not immediately clear, with India's Zee News saying 10 people had been detained.
But The Express said only six people were still in questioning, the authorities having reportedly already released two people due to lack of evidence.
The arrests took place in the Munger district of Bihar, which is in northern India.
The news comes a day after a Delhi court ruled that the Indian Mujahideen's Obaid-ur-Rehman should remain in custody amid investigations into the Feb. 21 double bombing in Hyderabad, reported Zee News. The blasts left 16 people dead and over 100 people wounded.
The NIA team went to Bihar in order to track down a SIM card registered under an alias that was believed used to communicate with those responsible for the attack, according to the Express.
