A Sikh youth was detained for a night in Delhi for allegedly attacking and verbally abusing Congress leader Jagdish Tytler at a wedding ceremony in the Mehrauli area on Saturday night.

The special executive magistrate granted bail to the youth on Sunday, ANI reported.

The incident took place after an argument, and Tytler escaped unhurt, according to reports.

Tytler is an accused in the 1984 anti-Sikh riots following the assassination of Indira Gandhi by her Sikh bodyguards on 31 October, 1984. According to the Nanavati commission report, the deaths in the riots are disputed, but nearly 3,000 Sikhs were killed across India. More than 2,000 were killed in Delhi alone.

The Nanavati commission, established by the Atal Bihari Vajpayee-led BJP government, submitted its report on the 1984 anti-Sikh pogroms, saying there was "credible evidence" against Tytler to prove he was probably involved in organising the attacks.

Tytler has also been accused of influencing witnesses and tampering with evidence.

The incident occurred just a day after a Delhi court refused to accept the CBI's closure report that gives Tytler a clean chit. The court directed the CBI to conduct further investigation into the allegations against the Congress leader by arms dealer Abhishek Verma, who has been cited as a witness in the closure report.

"The statement made by witness Abhishek Verma discloses an active role played by Jagdish Tytler in sending one Narinder Singh to Canada. Narinder is none other than the son of Surinder Singh Granthi, a key witness in the present case against Jagdish Tytler. It cannot be a sheer coincidence," The Asian Age quoted additional chief metropolitan magistrate Saurabh Pratap Singh Laler as saying.

"If the facts disclosed by Abhishek Verma are true, an inference may be drawn by the court against Jagdish Tytler in the present case. Thus, it becomes necessary to find out whether the facts disclosed by him are true or not," said the court.

Verma in his statement to the CBI has also said Tytler had told him in 2008 he had met the then prime minister, after which he got a clean chit for his alleged role in a 1984 anti-Sikh riots case, IANS reported.

The court has also directed the CBI to record the statement of other witnesses in the case.
