Jerrit G John was picked up from Nalasopara in neighbouring Thane district and was handed over to Mumbai Police yesterday.
The court of metropolitan magistrate has sought the medical report of the victim Aryanka Hosbetkar on the next date of hearing.
According to police, John, who owns a production house 'No Nonsense' and has produced-directed television serials, flung the chemical at the 26-year-old physiotherapist, who is also an international cyclist, at her residence at Adarsh Colony in Worli on Wednesday.
Hosbetkar had returned from a cycling expedition in the morning and was with her friends when John carried out the attack, police said.
The accused dragged Hosbetkar upstairs and allegedly hurled the chemical on her face as her shocked mother and friends watched.
She was later taken to a private hospital where she was treated and discharged on Thursday.
Hosbetkar had terminated her ten-month-old relationship with John after she came to know that he was married with a five-year-old son.
