A dead monkey is found in a hostel water tank at Assam Engineering College in Guwahati, and dozens of students develop minor illnesses after drinking the contaminated water. Reports say students had complained about foul-smelling water before the carcass was discovered.

According to the accounts, the discovery is made after students inspect the tank following repeated concerns about water quality. When students fall ill, they receive medical attention at local healthcare facilities, and the college administration responds by cleaning and disinfecting the tank. Students are also moved to another hostel while the situation is addressed.

Outlets differ slightly on the number of students affected and the timing details they foreground, but they broadly describe the same sequence: complaint about water quality, discovery of the dead monkey in the tank, illnesses among students, and remedial actions by the college.
