PHILADELPHIA (AP) Federal prosecutors are seeking to dismiss charges against a Temple University professor who was accused of scheming to provide secret U.S. technology to China.

The U.S. attorney's office in Philadelphia filed a motion Friday to dismiss four counts of wire fraud against the professor, Xi Xiaoxing (shee show-shing).

In its filing in federal court in Philadelphia, the government says only that the motion is based on "additional information" it received since the charges against the 57-year-old professor were filed in May.

His daughter, Joyce Xi, says the family is relieved the charges are being dropped. She says it's been a difficult time for the family.

Xi was chairman of the university's physics department until his arrest. He remains a faculty member. He is a naturalized U.S. citizen born in China.
