Dhaka , Bangladesh ( CNN ) -- A Bangladesh court on Sunday indicted the eldest son of a former prime minister and 29 others on charges related to alleged involvement in a 2004 deadly grenade attack on a rally led by the current prime minister , police and court officials said . Prime Minister Sheikh Hasina narrowly escaped the attacks , but Ivy Rahman , the wife of Bangladesh President Zillur Rahman was among 24 killed . The attacks are believed to have been carried out by an outlawed Islamist group called Harkat-ul-Jihad al Islami . The accused include at least two ministers in the cabinet of former Prime Minister Khaleda Zia , former chiefs of two state intelligence services and three former inspectors general of police . Twenty-two other people were previously indicted in the attacks . Zia 's eldest son , Tarique Rahman , 47 , now resides in England and will be tried in absentia , said Syed Rezaur Rahman , the state prosecutor . A judge set the trial date for March 28 . Police investigators say Tarique Rahman aided and abetted the Zia administration in planning the attacks and helping the assailants flee the scene . Rahman could face the death penalty if found guilty , according to the country 's penal code . Since the end of Zia 's tenure in 2006 , Tarique Rahman is facing 14 cases on charges of corruption and extortion . Zia 's youngest son , Arafat Rahman , was jailed for six years on a corruption and money laundering charge . He was also tried in absentia . Zia , who heads the opposition Bangladesh Nationalist Party and has served twice as the country 's prime minister , said political vendettas are to blame in both her sons ' prosecutions . The BNP and its allies have recently demanded midterm elections and launched an anti-government movement .
Tarique Ahmed is among the people killed in the deadly 2004 attack at a political rally . His mother , the former premier , recruited political opponents for his prosecution . He lives in England and will be tried in Pakistan , prosecutor says .
