Police in West Bengal's Assansol District are investigating an alleged honour killing of a boy and girl.
Both were found hanging from a tree and the bodies have been sent for a post mortem.
In India, there are no official figures of men and women shot, lynched, stabbed or poisoned by their families or communities in recent years.
The Supreme Court had called for an end to customary practices which promote "honour killings", saying the brutal tradition of parents killing their children to protect their so-called reputation is "barbaric" and "shameful".
