A Philadelphia man admitted in federal district court yesterday that he had sex with three underage females in Egypt from January 2004 to May 2007.

Authorities said Omar Rashaad Bey, 33, of South Philadelphia, impregnated two of the victims when they were 15 and both bore Bey's sons at the same age. The births occurred in Egypt in February 2006 and March 2007.

Federal law makes it a crime for a U.S. citizen to travel abroad to engage in illicit sex with persons under the age of 18.

Bey allegedly entered into "purported Islamic marriages" with the two women he impregnated, according to prosecutors.

Bey, a U.S. citizen, wore a white skullcap, white robe and sandals to the plea hearing. He told U.S. District Judge Jan DuBois he was not currently married, had fathered 12 children, ages 6 months to 15 years old, and was employed as a regional manager for a maintenance company.

Bey pleaded guilty to three counts of engaging in illicit sex in foreign places. He remains free on $100,000 unsecured bond pending sentencing. DuBois set sentencing for Jan. 7.

Bey faces at least three years in federal prison under preliminary advisory guidelines.
