Dhaka, Oct 27 (PTI) Several influential leaders of Bangladesh Nationalist Party were involved in the 2004 grenade attack on Prime Minister Sheikh Hasina and they used banned Harkatul Jihad (HuJI) to carryout the plot, according to a media report today.

The 'Daily Star investigation' claimed the "chilling conspiracy" to kill Hasina was hatched at Hawa Bhabhan, the office of Zia's elder son Tarique Rahman.

"The Awami League was branded as the archenemy of the country and Islam and it was recommended that its President Sheikh Hasina must die," the paper quoted the conspirators as saying.

"(Ex-junior minister for Home Litfuzzaman) Babar supplied the grenades (while) HuJI was used as mercenary group," the report said.

The Daily Star said the report was based on a "highly privileged document" it obtained and information collected by a reporter of the daily from investigators and intelligence officials involved with the probe over the last five years.
