According to the police, caretaker Sumit Arora, 30, came to the institute along with two of his friends in a drunk condition around 11 pm last night.
He then abused the inmates and beat some of them.
After beating the victim, Arora went off to sleep on a nearby bed. When he woke up in the morning, he realised that the victim had died and he ran away from the spot, the police said.
The owner of the centre was informed by the inmates about the incident this morning and the police were subsequently informed.
