Two schoolgirls have reportedly been found hanging from two ends of the same rope on a tree in Assam's Karimganj district.

The girls had been missing since Wednesday evening, the police said.

A relative of one of them discovered the bodies on Thursday morning, barely two kilometres from the border with Bangladesh.

Locals suspect that the girls were first raped and then killed. The police said a post-mortem will determine if that is correct.

"We have recovered the bodies and sent those for postmortem and forensic test," said Nabin Singh, a senior officer handling the case.

In May, two teen girls who were cousins were found hanging from a mango tree in Uttar Pradesh's Badaun district. Although their families alleged the girls had been gang-raped and then hanged alive, the CBI, which is investigating the case, says evidence recovered does not prove sexual assault.
