the country "from a foreign country" or indigenously manufactured by "highly-skilled foreign hands" who "hired" the perpetrator(s).

"The Hezbollah, a Shiaiite terrorist outfit with roots in Lebanon, has no base in the country. There is a very strong probability that the attack was carried out at their behest and through their funds but executed by a well-trained militant of Pakistan-based outfit for considerable payment," said a senior police officer.
However, investigators are in the dark about the identity of the motorcyclist who had stuck the bomb on the embassy vehicle.
Five persons, who own red motorcycles, were picked up for questioning today.
Gopal Krishnan, a resident of east Delhi's IP Extension area, told investigators he had seen a biker wearing a helmet and a red jacket and riding a red motorcycle sticking a palm size, square shaped whiteish device on the car.
Delhi Police commissioner BK Gupta said, "One biker who was captured tailing the Innova car in a CCTV camera in front of Israeli embassy approached us on his own. He was let off after questioning."
Even as the commissioner ruled out the role of the Indian Mujahideen (IM) in the attack, sources indicated that the attack was executed by operatives of either Jaish-e-Mohammad (JeM) or Lashkar-e-Toiba (LeT).
Police said the executor of the attack was a "well-trained militant" with "expertise and experience" in handling explosives and sophisticated explosive devices.
"Both these organizations are well aware of the country's urban landscape because of their involvement in similar incidents perpetrated in the past," said the officer.
As Hindustan Times had reported on Monday, the 'sticky bomb' was modelled on the concept of a 'destructive incendiary device', had an arming switch and a self-destruct mechanism timed between 5 and 10 seconds.
Sources said that though the explosion sent the targeted Innova up in flames, the fuel tank of the vehicle was fortunately intact.
"It seems that the executor wanted to combine the effects of the sticky bomb with that of an Improvised Explosive Device (IED) by turning the car into a car bomb and cause maximum damage to commuters and adjacent buildings," said the officer.
Gupta said investigators were seeking CCTV footage from Israeli embassy and Canadian embassy.
