Metropolitan Magistrate Geetanjali Goel, rejected the teacher Dilip Soloman"s plea that he be released on probation, pointing out that the move would send out a wrong signal to the society.
The court convicted Soloman under Section 354 (assault or criminal force on a woman with intent to outrage her modesty) and Section 509 (word, gesture or act intended to insult the modesty of a woman) of the Indian Penal Code.
The prosecution said, Soloman had molested the student on Feb 27, 2004 and Mar 19, 2004 during the lessons.
She then told her mother about it and her parents lodged an FIR at Chanakyapuri police station.
An in-house inquiry conducted by the music school reportedly went in favour of the accused.
The family then moved the Delhi High Court, which ordered a re-investigation.
