The victory of their anti-factional current, with the support of Antun Mavrak, secretary of the CPY Provincial Committee for Croatia and Slavonia, enabled the consolidation of party ranks.

Following the assassinations, the ensuing protests intensified police persecution of opponents of the regime, especially HSS members and communists.

In Zagreb, meanwhile, the management of the Workers' Cultural Society, of which Hebrang was a member, was arrested and served a month in prison.

Hebrang was arrested again on September 7, 1928, together with Mihail Vraneš, in Zagreb, in front of the house in Gundulićeva Street, where the secret Party archives were located.

At that time, communism, under the State Protection Act, was characterized as a coup d'état, which made it impossible to punish Hebrang more leniently.

[2] In 1942, he was captured by the Ustaše in house of Ivan Srebrenjak and sent to Stara Gradiška concentration camp, where he was later exchanged along with his future wife, Olga, for several Ustasha officials.

He also helped form the State Antifascist Council of the National Liberation of Croatia (ZAVNOH) and served as the vice-president.

[3] On 20 September 1943, ZAVNOH unilaterally issued a declaration that Istria, Rijeka, and Italian-occupied Dalmatia were part of Croatia without the prior approval of the national AVNOJ.

The whole economy, the creation of a system and the formulation of the strategy of development in the Five-Year Plan, was in the charge of Andrija Hebrang.

On 17 January 1947, Kardelj stated to the Central Committee of the Communist Party of Croatia that Yugoslavia would be industrially stronger than Austria and Czechoslovakia.

In May, he was accused of collaborating with the Ustashe and the Gestapo to sabotage Yugoslavia and spy for the Soviets after Tito broke with Joseph Stalin.

[6] Not long after Hebrang's arrest, his wife Olga was sentenced to twelve years in prison, and his children were sent to live with his sister, Ilona, in Zagreb.
