Muzaffarnagar: Four stray cows, locked inside a school campus shut for the annual summer vacation by farmers to keep them away from their crops, died due to hunger in Shamli district, police said Monday.

Eight cows were locked inside the government-run school campus in Karonda Hathi village a few days ago by some farmers. Police said four of them were found dead on Sunday and others have been rescued.
