Attempts to lift the lorry, of missing Kozhikode man Arjun, from the Gangavali River will begin Thursday morning. The update comes after the Karnataka Police confirmed the presence of a truck on the river bed, at a depth of 15 feet, about 20 metres from the banks.

Karwar MLA Satish Sail said a military-grade drone from Delhi will be brought via train for the completion of the mission on Thursday.
Two others also went missing in the landslide at Shirur on July 16.

Earlier, Karnataka Revenue Minister Krishna Byre Gowda said: "One truck has been definitively located in the water and the naval deep divers will attempt anchoring shortly. The long-arm boomer excavator will be used to dredge the river. An advanced drone-based Intelligent Underground Buried Object Detection system was also deployed for search. The Coast Guard will do a helicopter search for missing bodies in the water."

A helicopter belonging to the Coast Guard did a search operation in the river amid heavy rain and wind in Shirur. The long boom excavator was used in the rescue operation since Wednesday morning. A sonar signal indicating the presence of metal parts was detected from the river earlier. A signal was also received during a radar check from the same area.

The Navy and disaster management forces are using advanced technology, including sonar and radar, in the search operation. The Navy on Wednesday released a side scan sonar image of Ankola landslide location.

The investigation initially used Ground Penetrating Radar (GPR), a geophysical method that uses radio waves to capture images below the Earth's surface. Four teams of experts from the National Institute of Technology (NIT) in Surathkal, Dakshina Kannada district, have also arrived to assist in the search.
