Police seek diamonds swiping prostitute (PHOTOS) Erika Cooper.

Police in New York said security cameras recorded a prostitute fleeing her client's hotel room after taking $500,000 worth of diamonds while he slept.

Police said Cooper was recorded fleeing by a security camera and she gave Kaiser her real phone number, which allowed them to identify her from mug shots taken after a previous prostitution bust.

Kaiser, a gem trader, said he has two partners who were also affected by the theft. He said he suspects he was drugged by Cooper.
