Indian investigators probing the role of David Headley in Mumbai terror attacks have stumbled upon evidence that the woman who had accompanied him during his trip to India in 2008 was his Moroccan wife.<br/><br/>Well-placed sources in the investigating said the woman, who had stayed at Mumbai's Taj Hotel, one of the targets of the 26/11 strikes, visited India for the first time in 2007 alone after coming from Pakistan and could have taken the photographs of the targets in Mumbai.<br/><br/>This information was shared with the FBI which allegedly feigned ignorance about the same. The sources said she came again to India in 2008, this time with Headley.<br/>Investigators suspect the woman could be a LeT activist and might have brought some documents along with her for Headley. <br/><br/>The Home Ministry, in the meantime, has issued an advisory to all states, where Headley had visited, alerting them that some of their vital installations could be targeted by terrorists.<br/><br/>
