WASHINGTON - The FBI on Thursday added the names of nine Chinese people and one other man to the list of those being sought for questioning about a possible terror plot targeting Boston.
FBI spokesman Joe Parris said the names "were developed as a result of the ongoing investigation" but did not signal that credible evidence has emerged indicating such a plot actually exists.
"Information is still uncorroborated and from a source of unknown reliability and motive," Parris said.
The names are part of the same anonymous tip that led authorities on Wednesday to announce that they are seeking to question four other Chinese and two Iraqis. The new names bring to 16 the people being sought for questioning.
Another federal law enforcement official in Washington, speaking condition of anonymity because of the ongoing investigation, said the tip was received by the California Highway Patrol. The tipster claimed the four Chinese - two men and two women - entered the United States from Mexico and were awaiting a shipment of "nuclear oxide" that would follow them to Boston.
The official said the nuclear oxide could be a reference to material used to make a "dirty bomb" that would spew radiation over a wide area.
U.S. Attorney Michael Sullivan of Boston said earlier Thursday that authorities had learned more background about the original four Chinese, but "it makes us no more alarmed this morning, this afternoon, than we were yesterday."
The four Chinese previously named by the FBI were identified as Zengrong Lin, Wen Quin Zheng, Xiujin Chen and Guozhi Lin. Authorities said none of the names had appeared on previous watch lists of terror suspects. The bureau also released pictures of those four but not of the others being sought.
One woman was among the nine Chinese names added: Yu Xian Weng, 40 or 41 years old. The others were all men: Quinquan or Quiquan Lin, 21; Liqiang Liang, 28; Min Xiu Xie, 27; Xiang or Xing Wei Liu, 22; Mei Xia Dong, 21; Xiuming Chen; Cheng Yin Liu; and Zao Yun Wang.
The final new name was Jose Ernesto Beltran Quinones, of unknown age or national origin.
