Washington ( CNN ) -- A senior U.S. official is denying allegations that American officials ignored warnings by the Moroccan-born wife of David Headley , a Drug Enforcement Administration informer in Pakistan who was convicted of helping to plan the 2008 terror attacks in Mumbai . `` She expressed concern about individuals that her husband was hanging around with , '' he said . `` 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 . '' He added , `` There was nothing specific . There was nothing necessarily to follow up on . '' The official , speaking on background because of the diplomatic sensitivity of the subject , said the wife `` walked into the U.S. Embassy in December 2007 . There was a follow-up meeting in 2008 . That was the last contact that we had with her . '' The attack occurred in November 2008 . An American former wife of Headley also expressed concern about Headley 's activities to U.S. investigators two years earlier , news reports say , but Headley was able to continue his contacts and training with militants in Pakistan . The senior U.S. official denied , however , that the information was ignored . `` We took what the wives told us seriously , '' he insisted . This official said the State Department shared the information with `` relevant '' U.S. agencies . He said he did not know whether that information was shared with Pakistan . He would not say whether the information was shared with India , although he added that , as a matter of course , the U.S. shares intelligence with India and did so both before and after the Mumbai attacks . Asked whether the State Department fully investigated the Moroccan wife 's concerns , the official said that since the United States has limited authority in a foreign country it `` checked out what she told us . '' He provided no details . Monday , State Department spokesman P.J . Crowley told reporters that if the United States had had specific information on possible planning for the Mumbai attacks it would have shared it with India . `` We would have absolutely provided it to the Indian government , you know , beforehand , '' he said . `` The fact is that while we had information and concerns , it did not detail a time or place of the attack . '' Any information she did provide was followed up on , Crowley said . `` We followed up on that information and provided it to relevant agencies across the U.S. government , '' he said at a State Department news conference .
The information received included `` nothing specific , '' a U.S. official says . In the case of the two men who were killed in an attack on a CIA base last month, it was not clear whether they had been working for al Qaeda or another group. Reports : A former wife had expressed concern about the man two years earlier .
