Satish Kumar was found unconscious at his residence in west Delhi's Bawana area Thursday morning.
He was taken to a nearby hospital where doctors declared him dead. The cause of death was due to consumption of a poisonous substance.
"No suicide note was recovered from his possession. Initial investigation suggests that he was depressed over some family issue," said a police officer.
According to the officer, Kumar, who worked as a driver in CISF and used to ferry Delhi Metro CISF officers, had come to his residence around 8.30 a.m. after completing his night shift.
