A "pregnant" woman who had been arrested by federal agents on a cocaine charge delivered sooner than expected: When Sgt. Vickie Nehlig searched the woman, Fairfax County Sheriff M. Wayne Huggins said yesterday, she found 2.2 pounds of high-grade cocaine strapped to her waist.

"She put her up against the wall, put her hands on her stomach and she said it just felt like a rock," said Huggins. "The cocaine had been sculptured to make it look like she was pregnant."

Nehlig said the cocaine was in a large plastic bag attached to the woman's abdomen with surgical tape under her black leather dress.

Another kilogram of cocaine was found after a search of the woman's purse, said Robert O'Leary, a spokesman for the Drug Enforcement Administration. He said the cocaine has an estimated street value of $800,000 to $1 million.

The woman, Ayo D. Ford, 21, of 2920 Second St. SE, was taken to the jail Friday after she was arrested at Dulles International Airport by DEA agents on a charge of possession of cocaine with intent to distribute.

O'Leary said Ford and a companion, Delbert Mobley, 31, of the same address, were arrested about 10:40 p.m. Mobley was arrested on a charge of aiding and abetting, O'Leary said. Both charges carry a maximum sentence of 20 years in prison and a $225,000 fine, he said.
