Police filed a reply in the court to John's application seeking discharge from the case.
His application would be heard next week.
John, who owns a TV production house called 'No Nonsense', was arrested in November 2012, and is in custody since then. He is accused of throwing a chemical at Aryanka Hosbetkar (26), an international-level cyclist, at her residence in Worli here.
The two were facing problems in their 10-month-old relationship after Hosbetkar learnt that John was married and had a five-year-old son. He wanted to marry her.
