New Delhi, Sep 12: In a tragic incident, a teenaged couple - both school students and apparently in a relationship - ended their lives Wednesday by jumping to death before a train in the capital, police said.

While the boy, 17, was a class 12 student in a government school, the girl, 15, was a class nine student of DAV school and both were supposedly in love. What forced the couple to take the extreme step is still being investigated, police said.

"It appears as if they were having an affair but there was some opposition. We are quizzing the families and will reach a conclusion soon," Sanjay Bhatia, additional deputy commissioner of police (crime and railway) told IANS.

According to police, the incident took place at 4:30 p.m. at a railway line in Narela, north Delhi where the couple resided.

The police have found no suicide note at the spot.
