Now convicted in 1984 riots case, the former Congress leader Sajjan Kumar appeared before a Delhi court.
The appearance came about amid tight security.
He had been convicted in another riots case by the high court.
Kumar, who is accused of instigating a mob to kill Sikhs, surrendered his mobile phone before the court following directions of the high court in its order convicting him on December 17.
The court adjourned the matter for January 22 after Kumar said his main counsel was unavailable.
In the case before the trial court, three persons — Kumar, Brahmanand Gupta and Ved Prakash — are facing trial on charges of murder and rioting pertaining to the killing of Surjit Singh in Sultanpuri.
The riots broke out after the assassination of former prime minister Indira Gandhi by her Sikh bodyguards on October 31, 1984.>
