But he declined to reply when asked if the ACC is taking a similar move concerning immediate past prime minister and BNP chief Khaleda Zia.

Tajul Islam Farook, chairman of Westmont Power Company, filed an extortion case against Hasina on Monday.

"We will collect information (about Hasina)," Manzoor Mannan said when journalists referred to the extortion case and asked him whether the ACC will investigate Hasina's alleged involvement in corruption.

"I will not answer any other question in this regard," he said when asked if the ACC would also collect similar information about Khaleda.

Replying to another question in this regard, Mannan said, "You are repeatedly asking what we are doing about high profile persons. We will collect information about them, about their wealth and then we will proceed following the process that we apply for others."

He also said the ACC now has a new list of 34 high profile corruption suspects. Its officials are collecting information about them and will ask them to submit wealth statements, if necessary. But he declined to disclose names of the 34.

Mannan also contradicted an earlier statement of ACC Commissioner Habibur Rahman, saying that the new list of 34 is not related to the second list of 50 graft suspects published in the media last month after receiving that from government sources.

Habibur Rahman last week told journalist that the 34 are on the second list of 50 corruption suspects.

Asked about this, Mannan said, "I don't know anything about the second list of 50."

The ACC collected the list of 34 from the task force, he said.

The government-formed National Coordination Committee headed by Communications Adviser Maj Gen (Retd) MA Matin started its work on February 4. The committee is responsible for combating corruption and crimes. Seven regional committees, and task forces across the country operate under the national committee.

The ACC has so far received 10,000 complaints from people and selected around 1,100 of those for its consideration, Mannan said.
