Media showed Umar Khalid leave JNU campus and surrender to police from where they were taken in a private security vehicle.
There was a heavy deployment of police outside Vasant Vihar police station, following the JNU students' arrest.
Earlier in the day, the duo were asked by the Delhi High Court to surrender and were not given any protection from arrest even as the Delhi Police Commissioner warned the five accused students that all options are open to act against them if they fail to cooperate.
While refusing to grant protection from arrest, the court asked both petitioners to give details of the date, place and time where they will surrender, to the court and that senior police officials will ensure their safety.
The High Court will on Wednesday hear the plea of the two students, who are accused in a sedition case along with JNU student union president Kanhaiya Kumar, seeking protection during their surrender to the police.
As the legal battle intensfied, a plea seeking immediate arrest of the five JNU students accused of raising anti-national slogans came up before the High Court which dismissed it after the petitioner sought to withdraw it due to convert it into a criminal public interest litigation (PIL).
