"We have left it all to almighty Allah," Shahin Akhtar Jharna, Khorshed's sister-in-law, yesterday said referring to probe into the slaying.

The investigators, however, expressed confidence that they will be able to solve the murder case that was filed by Khorshed's wife Jahan Akhtar. "We are hopeful that we will soon solve the case," said Investigation Officer (IO) Fazlul Kabir of Detective Branch of police yesterday.

Advocate Khorshed Alam, the law affairs secretary of Dhaka city AL, was gunned down in city's Tejgaon area by unknown assailants while he was on the way to his office on May 17.

Kabir received the docket of the case yesterday from the former IO Sub-Inspector Giasuddin of Tejgaon Police Station. Earlier on May 18, the case was transferred to DB.

The IO yesterday visited the spot and met Jahan Akhtar, the complainant.

"Jahan could not talk much as she has been ill since the incident," Shahin, Jahan's sister, said yesterday. When asked if an intra-party feud resulted in her brother-in-law's murder, Shahin said, "We never told the press anything like this, and we don't have any idea of who might be the killers."

Police sources had said that the investigators were also looking into whether any hostility he had earned from forming Kafrul Thana unit AL committee led to the killing.

Khorshed headed a seven-member committee, which was tasked with choosing the committee members.

Besides, the investigators are gathering information if he was in dispute with anyone for personal matters, IO Kabir said.

They are yet to extract any information from Ismail Hossain alias Sujon and Mohammad Sohel, the two arrestees who were placed on a seven-day remand each on May 18.
