70-year-old Tunda was hit on his back by the attacker whose attempt to slap the suspected terrorist on his face was thwarted by the police personnel escorting him.
He was produced in the court of Metropolitan Magistrate Jay Thareja, who decided to hold the proceedings in-camera after a lawyer started shouting slogans against Tunda in the packed court room leading to commotion.
Delhi police sought his custody for 10 days to question him regarding his alleged terror links but the court remanded him in custody for four days.
Tunda is one of the 20 terrorists India had asked the Pakistan government to hand over after the 26/11 Mumbai terror attack and is suspected to be involved in 40 bombings in the country. He is the first in the list to be arrested.
According to Delhi police, he is a well known LeT explosive expert wanted for his role in 1993 Mumbai serial train blasts, Delhi bomb blasts of 1997-98 and serial bombings in the state of UP and also at Panipat, Sonepat, Ludhiana and Hyderabad.
