The police suspect the couple might have taken the extreme step after their families disapproved of their relationship.
The couple were rushed to a hospital here after the incident last night, where the girl died, police said, adding that the condition of the youth is stated to be critical.
"As per preliminary investigation, the two were in a relationship, and going to get married this year. Their parents, however, were reportedly against it, which forced them to take the extreme step," a senior police officer said.
