MUMBAI: A 15-year-old girl allegedly strangled her mother to death with a karate belt after a fight over her studies in Navi Mumbai, the police said. The girl later tried to pass it off as a case of accidental death, they said.

The incident took place in Navi Mumbai's Airoli area on July 30.

On July 30, the girl informed the police that her mother fell and died, the official said.

During questioning, the teenage girl told the police that she had strangled her mother with a karate belt after a fight with her.
