Three live hand grenades and an improvised explosive device (IED) were found from an empty ground in Sadoupur village near Maharishi Markandeshwar University (MMU) which is close to Chandigarh-Hisar national highway (NH-152), police said on Sunday.
All the explosives, weighing around 1.5kg, were defused by a bomb disposal squad under a controlled environment in the abandoned area near Punjab-Haryana border, the police added.
There are a couple of private schools, along with the university, besides an industrial area and a railway track in the vicinity of the spot. The location is just 50 metres away from the highway.
The grenades were spotted by a labourer working in the area on Saturday evening, but the police were informed on Sunday morning, said superintendent of police Jashandeep Singh Randhawa.
