Bengaluru: The police team probing the discovery of gelatin near the Prime Minister's travel route to the Art of Living Ashram on Bengaluru outskirts had also found a circuit and a timer, police sources said on Tuesday.
State Home Minister G Parameshwara too indicated that "materials of similar nature" were found.
He also said that the National Investigation Agency is also interested in joining the probe.
Two gelatin sticks were recovered from a roadside near PM Narendra Modi's programme venue on Sunday, triggering heightened security measures and an intensive police investigation into their origin and whether there was any larger conspiracy behind their presence.
The 'explosive materials' were found in a cardboard box, sources said adding that there was a timer and a circuit.
They also suspected that those who tried to put it there could not assemble it.
The police had received a phone call first, at about 7 am on Sunday, where the caller said he has planted a bomb.
Based on the call, the police swung into action and arrested a man from Koramangala in the city.
Hours later, the police team spotted the gelatin box a few metres away from the highway from where Modi's car would have passed.
Speaking to reporters here, Parameshwara said, "One person, who telephoned the police that there is a bomb in the ashram, has already been arrested.
"Investigation is going on. Once the inquiry is complete and we get to know things, then it will be made known to the public." Regarding the timer and circuit board along with the gelatin sticks found, the Minister said, "They've (police) told me that some materials of similar in nature have been found." PM Modi was in Bengaluru on Sunday to attend the 45th foundation day celebrations at the Art of Living Foundation centre on Kanakapura Road near Kaggalipura.
Before the PM's arrival, during checking, two gelatin sticks were found on the side of a footpath nearly three kilometres away from the main venue. Further investigation is on, a police statement said.
The recovery came amid a seven-layer security arrangement for the PM's visit, with police and security agencies conducting route inspections for nearly a week in advance.
