Two gelatin sticks were recovered near a route linked to Prime Minister Narendra Modi's visit to Bengaluru on Sunday, police said, adding that the source of the explosives is being investigated.
The explosives were found near Tataguni, close to Vaderahalli Gate, within the limits of the Kaggallipura police station on the outskirts of Bengaluru, police said.
An Anti-Sabotage Check team conducting security inspections ahead of the Prime Minister's convoy movement found the gelatin sticks near a compound wall beside a bridge, about 20 metres from the roadside.
Following a threatening phone call early in the morning, Bengaluru police alerted security agencies and Ramanagara district police, and search operations were carried out at several locations linked to the Prime Minister's visit.
A 40-year-old man was detained from his residence near Koramangala for questioning, who allegedly made similar hoax threat calls during previous visits by senior political leaders and other VIPs to Bengaluru.
However, police said initial inquiry had not established any direct connection between the detained man and the gelatin sticks recovered near the route.
The gelatin sticks had been safely disposed of, and investigators are examining CCTV footage from nearby areas, analysing mobile call records and reviewing the detained man's background as part of the inquiry.
