A 65-year-old resident of Masuri in Ghaziabad died late on Friday after he fell down the stairs from the first floor of his house allegedly during an altercation with five students, one of whom was his tenant.
Jeet Singh's family has lodged a police complaint, accusing the five youths of murdering him.
Singh had let out his first-floor house in Masuri's Indargarhi to BTech student Manmohan Mishra around two months ago. Arguments would break out frequently between the two over Mishra's friends visiting the place to drink, police said.
On Friday, Mishra and four of his friends were allegedly drinking when Singh went upstairs. He and the five youths had a row.
"Singh had told them to not drink in his house. There had been frequent arguments over the matter. On Friday evening, a heated exchange of words led to an altercation," circle officer Ran Vijay Singh said.
The police said that during the altercation, Singh was pushed from the first floor. He then tipped over and fell down the stairs, causing critical head injuries.
"The head injuries led to his death. Later, angry local residents came to the house and nabbed two of the youths, both law students. They were beaten black and blue. They were later admitted to a private hospital and are being treated there," the officer added.
During the melee, Mishra and two others fled the spot and could not be arrested till late on Saturday.
"The two students are under treatment. No arrests have been made as yet because the police are investigating whether Singh was shoved deliberately or he fell down the stairs accidently," the officer told this correspondent.
Mishra, who is studying for a BTech degree at a Ghaziabad engineering college, is from Kasganj district in Uttar Pradesh.
