Badal questioned why the investigation had not identified those responsible even after 11 years and alleged that the AAP and Congress governments had used the sacrilege issue for political gains.
The SIT, investigating the police firing incident during a protest against an alleged sacrilege incident, is led by Inspector General of Police Naunihal Singh.
Both the accused were intercepted near Meera Bagh, Pashchim Vihar, in the early morning hours of Thursday. With their arrest, the total number of arrests in the case has risen to four, police said.
