Cairo ? None of the alarms and only seven out of 43 surveillance cameras were working at a Cairo museum where a Vincent van Gogh painting was stolen, Egypt’s top prosecutor said Sunday.

Thieves made off with the canvas, known by the titles of “Poppy Flowers” and “Vase with Flowers,” on Saturday from the Mahmoud Khalil Museum in the Egyptian capital.

Prosecutor general Abdel-Meguid Mahmoud told Egypt’s state news agency Sunday that the thieves used a box cutter to remove the painting from its frame. He blamed the heist on the museum’s lax security measures, calling them “for the most part feeble and superficial.”

The museum guards’ daily rounds at closing time were inadequate and did not meet minimum security requirements to protect internationally renowned works of art, he said.
