After Hussain's arrival in Chennai, he was picked up and subjected to sustained interrogation during which, the sources claimed, he spoke about a possible terror strike on the two consulates.
During interrogation, Hussain reportedly took the name of Amir Zubair Siddiq, who is counsellor (visa) at Pakistan high commission in Colombo, as his alleged handler and also said he had been chosen as he was engaged in human trafficking, making of forged passports and smuggling of fake Indian currency.
The sleuths recovered pictures of US and Israeli consulates showing various gates and roads leading to the two premises, the sources said, and claimed that these pictures had been mailed to his alleged handlers in Pakistan and its high commission in Colombo.
Cyber signatures showed that the pictures were downloaded at a computer within the premises of Pakistan high commission at Colombo and the same had been shared with Sri Lankan authorities, the sources claimed. Muhammad Daud Ehtisham, press attache, High Commission of Pakistan in Sri Lanka, has dismissed as speculative in nature the charge of ISI's alleged involvement in any attack plans.
Observing that this seemed to be a "malicious media campaign", Ehtisham has been quoted as having said that Pakistan and its state institutions are responsible entities and do not indulge in such activities.
The sources claimed that a proper sketch prepared about the roads leading to the two consulates were also uploaded and emailed in Portable Document Format (PDF).
