Ramu planted his mobile in Sheela’s bag to falsely implicate her in a crime. This act is classified under Section 192 of the Indian Penal Code (IPC), which defines "fabricating false evidence" as intentionally creating a false circumstance to mislead the court.
According to IPC, when a person causes a false situation to exist or makes false entries with the intent to mislead a judge or public servant, it constitutes fabricating evidence. Ramu’s conduct squarely fits this definition.
