As a member of the Lučko Anti-Terrorist Unit, he took part in early activities by the Croatian police forces including the Plitvice Lakes incident.

[1] In September 1991 Norac left the police force and moved to Gospić, where he took part in the assault against local Serbs and Yugoslav People's Army (JNA) units.

[2] In 1992 Croatian president and commander-in-chief Franjo Tuđman ordered his relief due to ever increasing rumours of war crimes committed against civilians under his command.

He went on to command Operation Medak Pocket, during which time war crimes against the local ethnic Serb population were committed.

[9] On 16 October 1991 Tihomir Orešković (Secretary of Lika Crisis Headquarters) called a meeting to organise the killing of ethnic Serb civilians in the area.

Norac reportedly attended the meeting, among a group of masked and unmasked soldiers and civil policemen, which later raided houses in Gospić and took custody of ethnic Serb civilians, informing them that they were to be interrogated.

Those murdered included Radmila Stanić, Branko Kuzmanović, Branko Štulić, Stanko Smiljanić, Radojka Diklić, Mirjana Kalanj, Đorđe Kalanj, Dane Bulj, Milan Pantelić, Mileva Orlović, Miloš Orlović, Radovan Barać, Ljubica Trifunović, Petar Lazić, Borka Vraneš, Bogdan Šuput, Dušanka Vraneš, Nikola Gajić and Željko Mrkić.

[11] On 5 March 2001, an indictment against Norac, Orešković, Stjepan Grandić, Ivica Rožić and Milan Canić was issued, accusing them of the murder of 50 civilians at Karlobag, Pazarište and Lipova glavica.

[13] On 20 May 2004, the International Criminal Tribunal for the former Yugoslavia (ICTY) issued an indictment against Norac (and Rahim Ademi and Janko Bobetko) for crimes committed during Operation Medak pocket in 1993.

"[14] Norac was accused of having "planned, instigated, ordered, committed or otherwise aided and abetted in the planning, preparation or execution of persecutions of Serb civilians of the Medak Pocket on racial, political or religious grounds", and of the "mutilation and desecration of the body of Boja Pjevać; the public killing of Boja Vujnović by burning her alive".

Norac was found guilty of failing to stop soldiers under his command from killing and torturing Serbs, and was sentenced to an additional seven years concurrent imprisonment.

[5] The Croatian state attorney's office launched a case on 17 December 2013 to force Norac to pay 111,000 euros, the amount awarded in damages to relatives of victims in two separate wartime incidents.
