The truckers and their helpers hailed from Haryana's Mewat district. They went missing in Assam's capital Dispur and their vehicles were later recovered by police.
Haneef, 42, a resident of Khedla Kalan village in Mewat's Ferozpur Jhirka sub-division was the driver of an edible oil tanker and his helper was Shakir, said Rahim Khan, father of Shakir.
Truck driver Kamrudeen, 50, from Agon village in Mewat area, and his helper Mushtak Ali were also missing, he said.
Ferozpur Jhirka is some 85 km from Gurgaon city.
"Both the tankers, carrying edible oil, had left for Dispur from Rajasthan's Nadbai area in Bharatpur district Aug 16," Rahim Khan said.
"I spoke to my son Aug 22 night, after that they are missing," he said.
"They (tankers) were about to reach their destination but a trader in Assam told them to wait for a day as there was a shutdown call for Aug 23," Rajesh Kumar, a transporter and owner of the tankers, told IANS.
He said that tankers full of oil were recovered by police Aug 24 and were in Dispur police's custody.
"We have already lodged a police complaint in Assam," he said.
