"We have got definite clues about the kingpin of the crime. He behaved like a sardar (chieftain) and posed as a CBI officer. He roped in five members from Mumbai, including those hailing from southern states," Cyberabad Police Commissioner Sandeep Shandilya said.
The senior police officer suspected that all the six interstate criminals, who met in jail, came together to execute their plan.
The gang leader and the SUV is under discrete surveillance of a strong police team and it has also been found that the offenders also used one bike while committing the crime.
"We are tracing out their entire movement from December 23 till 28. We have with us footages from 35 CCTV cameras (installed along the highway). Through CCTV footages, it was found that an SUV and a bike were used on the same route to do recce," the Commissioner said.
"After the offence, the motorcycle was moving two kms ahead of the SUV and piloted it to Wadi area. There, all six of them got down with the booty and left to Mumbai by train and parked the four-wheeler near Wadi in their den. We are waiting for an opportunity for them to come together," Sandeep added.
