On Wednesday, Indian Prime Minister Narendra Modi was tapped on a flyover by demonstrators in East Punjab for 20 minutes, in what was described as a security breach.
Mr Modi was on his way to a memorial in the northern state when protesting farmers stopped the road.
They were calling for the resignation of a minister whose son is suspected of killing farmers.
“This was a severe breakdown in the PM’s security,” the federal home ministry said in a statement.
Mr Modi was also set to speak at a campaign event in Ferozepur.
The prime minister’s convoy, however, was forced to return to the airport owing to a security lapse, according to the home ministry.
