Ms Mirza is to be engaged to a family friend on Friday
A second man has been detained after professing his love for Indian tennis star Sania Mirza at her Hyderabad home.
Ajay Singh Yadav told the police that he had been in love with Ms Mirza - ranked 85th in the world - for five years and wanted to marry her.
On Wednesday another man, Mohammad Ashraf, was arrested after threatening to kill himself if Ms Mirza did not marry him. Both men are in custody.
The tennis player is to be engaged to a family friend on Friday.
Security has been tightened at Sania Mirza's bungalow in the upmarket Banjara Hills area of Hyderabad.
The police said Ajay Singh, from Noida in Uttar Pradesh, arrived in the city in the morning and rushed to Banjara Hills, saying he wanted to meet the tennis player.
When he did not go away despite warnings, the police took him in to custody.
"I have loved her for the last five years, and want to marry her," Mr Singh said, remaining cool and composed.
Based on an identity card he carried with him, the police identified him as a student at the Dronacharya College of Engineering in Noida.
It was a repeat of Wednesday's drama, in which Mohammed Ashraf, an engineering student from Kerala, tried to enter Ms Mirza's house and threatened to commit suicide if her engagement was not cancelled.
Mr Ashraf, a resident of Manjeri in Malappuram, said he wanted to "propose" to Ms Mirza. He said he fell in love with her two years ago, when he watched her playing tennis in Bangalore.
The Banjara Hills Police charged Mr Ashraf with offences including trespass, criminal intimidation and uttering words or making gestures outraging the modesty of a woman. He was sent before a local court, which remanded him in custody for 14 days.
Ajay Singh will also appear in court and be sent to the same jail where Mr Ashraf is lodged.
