A 21-year-old student from northeast was found dead here under mysterious circumstances, police said Friday.
Thangsonalian, who was pursuing a course in stenography, was found dead on the staircase outside his house in south Delhi's Munirka area Thursday night.
According to initial investigation, Thangsonalian was under the influence of alcohol and returned to his house after watching a match at Ambedkar Stadium.
"Prima facie it seems that due to alcohol consumption, he might have slipped and fell down from the staircase, which might have caused his death," a police official said.
"But we are yet to get his post-mortem examination report which will reveal the exact cause of the death," the official added.
The official said police did not rule out the possibility of murder.
This is the third case of death of students from northeast in the national capital since Wednesday.
