One escaped from jail twice in the past year and the other was dressed for a basketball game.

William Davis, 25, of Allentown, Pa., the escape artist, and Kasam Hennix, 39, of Easton , Pa., wearing matching lavender shorts and Air Jordan athletic shoes, appeared Wednesday before U.S. Magistrate William I. Garfinkel in Bridgeport and were told they were being detained without bond and would be indicted shortly for their roles in the April 11 robbery of $4 to $5 million from Lenox Jewelers on Black Rock Turnpike.

"There is a warrant for Mr. Davis' parole violation," Assistant U.S. Attorney Tracy Dayton told the judge.

Davis twice escaped from the Wernersville Correctional Center in Berks, Pa. His last escape occurred on April 8 -- three days before the Fairfield robbery.

The pair now join Jeffrey Houston, 26, of Allentown, Pa., and Christopher Gay, 27, of the Bronx, N.Y., facing charges of conspiring to kidnap two Lenox Jewelers employees from their Meriden home on the night of April 11, driving them back to Fairfield and then forcing them at gunpoint to open the store and its safe.

Inside the store, police said, the robbers stole nearly $5 million in expensive watches and other costly gems. Only $100,000 has been recovered, according to authorities.

A fifth man, Timothy Forbes, 31 of Allentown, Pa., is in custody, but has yet to be brought to Connecticut to be informed of the charges against him.

Fairfield and Meriden police, who are working with the FBI and U.S. Marshal's service, said they unraveled the case with the help of an eagle-eyed neighbor. That neighbor, who lives in the same Eastgate Condominium complex in Meriden as the Lenox employees, saw a suspicious car twice in the early morning hours of March 30 and wrote down the license number, police said.

Police traced the plate to a rental car agency in Pennsylvania which provided them with the cell phone numbers the customers used. Once authorities had the cell phone numbers they then traced it to subscribers, obtained the call records and began identifying the suspects, police said.

"This is an outstanding example of the positive results that occur when investigative agencies from all levels of government and jurisdictions work together for a common goal," said U.S. Marshal Joseph Faughnan. "Fortunately, these individuals were arrested before committing similar crimes that place the lives of innocent persons at risk."
