According to police, Rajpal, who ran a tea stall in the Saroorpur Industrial area, was chatting with customers when a youth passed a casual comment asking why he was gossipping.
To this, Rajpal replied in a similar tone, they said.
Angry over Rajpal's retort, the youth went away and later returned with a few accomplices.
According to eyewitnesses, the accused youths, all around the age of 25, thrashed Rajpal with bricks and stones besides kicking and punching him.
"The beating was so brutal that the men died on the spot," Mujesar SHO Rajinder Singh said.
