Police have registered a case against six persons for allegedly attempting to grab land of a private school in Maharashtra's Thane district and extort money from its management, an official told news agency PTI on Wednesday.

The school management approached the Kalwa police on Tuesday with a complaint alleging the accused started digging work in the school premises on September 29, 2022 under the pretext of taking up construction of chawls (tenements) and rent them out, the official from Kalwa police station told PTI.
