The body of a bank official in his late 20s was found in his paying guest accommodation in Salt Lake’s Labony Housing Estate on Monday evening.

P. Samwrith, from Amberpet in Hyderabad, was declared dead at Bidhannagar Sub-divisional Hospital.

Samwrith had been suffering from anxiety and appeared depressed for the past few days, his flatmates told cops.

“A homemade suicide bag using a helium cylinder has been recovered…. It is still not clear how he had sourced it,” the police said.

An officer said helium cylinders were used to fill balloons.

The police have found a suicide note in the flat and have alerted Samwrith’s relatives about his death.
