Andhra Pradesh Police claimed to have made progress in their probe into the twin blasts in Hyderabad with the identification of two Bangladeshi nationals who were allegedly involved in the terror attacks.

Police have learnt that Masiluddin and Hussain, both Bangladeshi nationals, were staying with Rizwan Ghani, a suspect in the twin blasts who is at large, ACP B Redanna told PTI on Sunday.

The photos of the two suspects were released in Hyderabad.

Earlier, the Special Investigation Team had released the sketch of a suspect involved in the blast at Lumbini Park on August 29, four days after the explosions that killed 43 people.

The ACP said those who furnish information about the duo, would be rewarded 'suitably.'

The duo was the roommate of Rizwan who is absconding ever since his house was raided on September one, police said. While Masiluddin left the city after Mecca Masjid blast on May 18, Hussain, said to be relative of Ghazi, left the city after twin blasts on August 25, he said.

The trio were staying illegally in the city, the ACP said.

During the course of investigation, it was found that Ghazi's brother was studying in one of the madrassas in the city, he said, adding, "We have yet to get more details about him."

Meanwhile, police is interrogating his sister Shahi Rafsanjani after her arrest last week for travelling without valid documents.
