A full inventory of the Egyptian Museum has found that looters escaped with 18 items during the anti-government unrest, including two gilded wooden statues of famed boy king Tutankhamun, the antiquities chief said Sunday.

The 18-day uprising that forced out President Hosni Mubarak engulfed the areas around the museum, on the edge of Cairo's Tahrir Square. On Jan. 28, as protesters clashed with police early on in the turmoil and burned down the adjacent headquarters of Mubarak's ruling party, a handful of looters climbed a fire escape to the museum roof and lowered themselves on ropes from a glass-paneled ceiling onto the museum's top floor.

Around 70 objects — many of them small statues — were damaged, but until Sunday's announcement, it was not known whether anything was missing.

Antiquities Minister Zahi Hawass said the museum's database department determined 18 objects were gone. Investigators searching for those behind the thefts were questioning dozens of people arrested over several days after last month's break-in.

The most important of the missing objects is a limestone statue of the Pharaoh Akhenaten standing and holding an offering table. Akhenaten is the so-called heretic king who tried to introduce monotheism to ancient Egypt.

"It's the most important one from an artistic point of view," said museum director Tarek el-Awady. "The position of the king is unique and it's a beautiful piece of art." During Akhenaten's so-called Amarna period, named after his capital, artists experimented with new styles.

Also gone is a gilded wooden statue of the 18th Dynasty King Tutankhamun, Akhenaten's son, being carried by a goddess. Pieces are also missing from another statue of the boy king wielding a fishing harpoon from a boat.

"We have the boat and the legs of the king, but we are missing other parts of the body," el-Awady said. "We are looking everywhere for them — around the museum, outside, on the roof, from where the thieves got into the museum."
