The man who attached a bomb to the car of the Israeli diplomat on February 13 reached the Indira Gandhi International Airport a little over an hour after the explosion and waited six hours for a flight to Kuala Lumpur,officials said on Monday. Houshang Afshar Irani,the Iranian who is suspected to be the bomber,rushed to the airport immediately after the terror strike. The explosion was reported at 3.20 pm on February 13 and investigators have found records of Irani entering the airport around 4.30 pm. It was found during investigations that Irani checked in at the airport counter around 4.30 pm,just a little over an hour after the bomb blast. So,even before immigration authorities could be alerted,he was through with his travel documents and could flee India, an official said. The police claimed it managed to unravel the conspiracy related to the attack on Aurangzeb Road an Israeli diplomat and three others were injured in the explosion after they found the number of Irani in the telephone list of Sedaghatzadeh Masoud,one of the members of a terror module planning an attack in Bangkok. Malaysian authorities detained Masoud on February 15 when he was trying to board a flight to Iran. He fled Bangkok after an Iranian lost his legs when a bomb he was carrying exploded. It was with the help of the call details of Irani that the police arrested Delhi journalist Syed Mohammed Ahmad Kazmi,saying he facilitated the attack. Last week,Delhi Police Commissioner B K Gupta said Kazmi helped the attack team. The other two accused in the attack,Syed Ali Sadr Mehdian and Abolghasemi Mohammad Reza,left the city before the blast. The return ticket of Mehdian was booked by Kazmi. Documents to this effect have been seized from the travel agency concerned, Gupta said.
