Police have accused Mufti Izharul Islam Chowdhury, principal of Jamiatul Uloom Al-Islamia Madrasa and Nayeb-e-ameer of Islamist group Hefazat-e-Islam, and his son Mufti Harun Izhar in two cases filed in connection with an explosion at the madrasa on Monday. There are several programs of prime minister Sheikh Hasina 12 october, in Chittagong. Experts said that it is not beyond doubt if her programme was their main target to attack her .
They have also included 10 other identified and many unidentified people in the cases filed with Khulshi police station on Tuesday. Meanwhile, Habib, 25, one of the at least 7 injured in the explosion and later arrested, succumbed to his injuries at Chittagong Medical College Hospital early on Tuesday.
Banaj Kumar Majumder, additional commissioner of Chittagong Metropolitan Police, said they had recovered another hand grenade from the place of explosion at the madrasa locally known as Lalkhana Bazar madrasa on Tuesday morning. Said,“We are conducting drives to arrest the other accused in the cases."
Khulshi police station OC Mainul Islam said Sub-Inspector Golam Newaj had filed a case under the explosives act, accusing 12 people, including Izhar and his son Harun, and many unidentified others; and another under the acid control act, accusing Izhar and Harun in connection with the recovery of picric acid from Izhar’s residence.
According to Wikipedia, picric acid, also called 2,4,6-trinitrophenol, pale yellow, odourless crystalline solid that has been used as a military explosive, as a yellow dye, and as an antiseptic. Picric acid (from Greek pikros, “bitter”) was so named by the 19th-century French chemist Jean-Baptiste-André Dumas because of the extremely bitter taste of its yellow aqueous solution. Percussion or rapid heating can cause it (or its salts with heavy metals, such as copper, silver, or lead) to explode.And Banaj Kumar Majumder said it was used to amplify the magnitude of explosion.
An official of Chittagong Metropolitan Police said they had raided Darul Uloom Madrasa in Chandanpura area in the afternoon, following a lead on Izhar’s presence, but the Hefazat leader had not been there. “We have arrested five persons for interrogation,” he told .Later, the police raided Mufti Izhar’s residence at night and seized 18 bottles of picric acid and arrested five persons, including four teachers of the madrasa.
Picric acid was first obtained in 1771 by Peter Woulfe, a British chemist, by treating indigo with nitric acid. It was used as a yellow dye, initially for silk, beginning in 1849.As an explosive, picric acid was formerly of great importance. The French began using it in 1886 as a bursting charge for shells under the name of melinite. By the time of the Russo-Japanese War, picric acid was the most widely used military explosive. Its highly corrosive action on the metal surfaces of shells was a disadvantage, however, and after World War I its use declined. Ammonium picrate, one of the salts of picric acid, is used in modern armour-piercing shells because it is insensitive enough to withstand the severe shock of penetration before detonating.Picric acid has antiseptic and astringent properties. For medical use it is incorporated in a surface anesthetic ointment or solution and in burn ointments.
Picric acid is a much stronger acid than phenol; it decomposes carbonates and may be titrated with bases. In a basic medium, lead acetate produces a bright yellow precipitate, lead picrate.
Police on Tuesday produced Habibur Rahman, Mohammed Ishaque, Monir Hossain, Abdul Mannan and Tafsir Ahmed all arrested on Monday in connection with the explosion before the court and placed a prayer for seven days’ remand.Metropolitan Magistrate Nur-e-Alam Bhuyan fixed Wednesday for hearing the remand prayer.
A massive explosion rocked Lalkhan Bazar Jamiatul Ulum Al Islamia Madrasa at about 11am on Monday, leaving at least five persons critically injured. The police recovered three hand grenades and huge materials for making grenades from a room of a dormitory of the madrasa where the explosion had taken place.
The law enforcers had earlier arrested four injured Nurun Nabi, Salman, Zubair Ahmed and Habib when they had been receiving treatment at two private hospitals after the incident.A security personnel on duty at the hospital said Habib had talked to them even an hour before he died.
Requesting anonymity, he said Habib had told him that the explosion took place soon after Nurun Nabi had kept his bag coming into the room.Nabi, a diploma engineer who sustained 90% burn injury, was shifted to Dhaka for treatment late Monday.
