Special judge Harish Dudani dismissed the appeal of west Delhi resident Sonu, saying the offence he committed will leave scars in the mind of the victim for years to come.
"Looking at the gravity and manner of commission of offence, the sentence awarded to appellant (Sonu) by trial court is not disproportionate to the offence committed by the appellant," the court said.
The trial court had in December 2016 sentenced Sonu to three years of rigorous imprisonment under section 379 of the Indian Penal Code (Punishment for theft).
It had also sentenced him for two years of jail under section 356 of IPC (Assault or criminal force in attempt to commit theft of property carried by a person) and said the sentences shall run concurrently.
Onlookers apprehended Sonu but his accomplice managed to escape on the bike which was not having any number plate.
Sonu had denied all the allegations but failed to lead any evidence in his favour.
