And finally, it was the identification of a secret phone number used by the main suspects to communicate between themselves, that became the turning point in the investigation.
The police team finally zeroed in on a house in Kozhikode where the accused were hiding and arrested four people including Joseph alias Jaison alias Babu, the kingpin of the operation along with three others including a woman and recovered 80% of the stolen gold and money.
It is the first recovery in the crime history of Kerala of so much stolen property.
The police further said that the remaining items would be traced within days as the accused have already confessed their location. The official arrest was formally announced on 28 February 2008 by K S Jangpangi, the additional director general of Kerala police.
It is widely considered to be a credit to Kerala police that they solved the biggest robbery in the state within a short period and with the first recovery of so much stolen property.
The leader confessed that the crime was inspired by the Bollywood movie Dhoom. In the movie also, the robbers made a hole in the ground floor of the bank and got away with the valuables during the new-year event.
