WASHINGTON: The United States acknowledged Monday that a wife of a key figure in the 2008 Mumbai attacks raised concerns about him months before the plot was carried out, but said the information was not specific.US State Department spokesman Philip Crowley added that the information about David Coleman Headley was forwarded to US government agencies and to the Indian authorities before the attacks that killed 166 people in November 2008.Crowley, asked about a report Saturday in The New York Times, said US officials had two meetings with one of "Headley's spouses in late 2007 and early 2008."She provided "some information. We followed up on that information and provided it to relevant agencies across the US government," he said."Did we share information with our security partners, including India, prior to the Mumbai attacks? The answer is yes," Crowley added."At the same time, the information was not specific," he said.If the US government had had specific information, it "would have absolutely provided it to the Indian government beforehand," he said."The fact is that while we had information and concerns, it did not detail a time or place of the attack," Crowley added.When asked why Headley was not arrested after the meetings, Crowley replied: "I can't answer that question."A senior US official said Headley's wife gave the information to the US embassy in Pakistan in December 2007, and that US officials asked for and obtained a second and last meeting with her in January 2008."She expressed concern about individuals that her husband was hanging around with," the senior US official told reporters on the condition of anonymity."She did say that she had concerns that they were involved in a terrorist plot. She had no details about who he was associated with or what they might be contemplating," the official added.Headley, the son of a former Pakistani diplomat and a white American woman, is being held in the United States.He confessed to plotting the Mumbai attacks and in exchange for pleading guilty, US prosecutors agreed he would not face extradition to India or the death penalty.The Washington Post reported Friday that another wife of Headley warned FBI agents in August 2005 that her husband had undergone intensive training with Lashkar-e-Taiba and was in contact with extremists.
