The explosion sound shook the surrounding area, causing panic and fear among residents, wile damaging nearby vehicles. A security source, Mohammed Radwan, told Arabstoday that an official investigation had already begun, and that this was the twelfth attack on security officials who served under slain dictator Muammar Gaddafi. \"Such operations are frequent in Benghazi and Derna (300km east of Benghazi)...I clal on the authorities to preserve the lives of these officials because not all of them are guilty of torture, if that is what is behind the assassination attempts,\" said Radwan. The spokesperson for the National Security Directorate in Benghazi, Magdi Aorafy, said that the bomb was triggered by Kaduz turning the key in the car\'s ignition. He was declared dead at the Benghazi Medical Centre. Aorafy said they had enough evidence to warrant a formal investigation, while saying Benghazi, the hub of the pro-democracy revolution that ousted Gaddafi, was the only Libyan cities beset by these problems.
