Police said the message written on a piece of paper read: “Modi Ji, do not consider us the same people as we were during 1971 (Indo-Pak war). Now each and every child is ready to fight against India.”
The note was apparently signed by the Pakistan-based militant group Lashkar-e-Taiba, “so we are investigating the matter very seriously,” Pathankot police inspector Rakesh Kumar told AFP.
It is not the first time that pigeons have become entangled in the decades-old rivalry between the two nuclear-armed nations.
Just last year, the Indian police seized a pigeon on suspicion that it was being used for espionage by Pakistan and also X-rayed it to check for any spy camera, transmitter or hidden chip.
In 2013, Indian security forces found a dead falcon fitted with a small camera and in 2010 another pigeon was detained over fears of espionage.
