The name of a former girlfriend of Rizwanur Rehman, the computer graphics teacher who was found dead on railway tracks just a month after his marriage to a Hindu girl, surfaced on Wednesday during investigations by CBI.
Briefing newsmen, CBI DIG Satish Golcha said the former girlfriend, Pompi Roy, was questioned as also Pradip Todi, the brother of Rizwanur's father-in-law Ashok Todi, for a second time.
CBI sources said Pompi seemed to be an important figure in the case. In the last few hours before Rizwanur's death on September 21, he had made five calls to her.
"One call was made to Pompi, one to rights activist Sujato Bhadra, one to his student Madhavi Chandak and another to his friend Sapnil. The fifth call is not known," the sources said.
"Rizwanur spoke to Pompi for a long time and she is an important figure in the case," the sources said.
The CBI also checked Rizwanur's bank account and collected a mobile phone and two letters from a locker.
Golcha said CBI interrogated the mother of Priyanka, wife of Rizwanur. "Her statement is very important in the case", he added.
He said "in the next 48 hours a lot of things will become clear."
