The gang of five was mercilessly beating a truck driver with iron rods in an attempt to rob his truck at Dharuhera flyover yesterday, Rattan Singh, SHO Dharuhera said.
The police patrolling team reached the spot following which two of the accused, Sammi and Ahzar fled from the spot in a car, he said.
Though the remaining three also tried to escape, two of them died after jumping from the flyover while the fifth accused was caught, police said.
The arrested accused Mubarik told the police that they used to sell the looted trucks in Mewat.
"There are many gangs actively involved in cattle smuggling and truck robberies in the belt of Sohna and National Highway-8 at the belt of Mewat region. This Mewati gang has looted trucks that were in turn used in illegal stone supplying and boulders from one place to others," Singh said.
A team has been made and a manhunt is on to nab the absconding accused, police added.
