A case involving a bomb attack targeting a tourist site in Egypt's Upper Egyptian city of Luxor was referred to the State Security prosecutors on Tuesday for investigation, the prosecution said in a statement.
A suicide bomber attacked a tourist bus near Luxor's Karnak temple in June. The incident left the bomber and a gunman involved in the attack dead.
Assistant Prosecutor General Zakaria Abdel Aziz Othman issued the referral order to swiftly look into the case, the statement read.
The State Security, a police branch that has its own prosecution and courts, was renamed to Homeland Security after the January 2011 uprising.
The State Security prosecution, however, retained its name. Typically, State Security prosecutors look into cases that affect national security.
Militancy inside Egypt has seen a significant rise since the military ouster of Islamist president Mohamed Mursi in July 2013, which was prompted by mass protests against his rule.
