[1] The two men, Blago Mikulić and Ivan Vujičević, demanded that the Yugoslav authorities release the convicted bomber Miljenko Hrkać, who was imprisoned in Yugoslavia and that he be brought to the Franco-controlled Spain with $20,000 in his pocket.

[2] The Yugoslav ambassador to Stockholm, Vladimir Rolović, criticised the Swedish police in the media and saying they did not take the terrorist threat seriously enough, claiming that the Croatian separatists belonged to Ustaše, an organization that collaborated with Nazi Germany during World War II.

[2] A few months later, on 7 April 1971, at the Yugoslav Embassy on Strandvägen 7B in Stockholm, Miro Barešić and Anđelko Brajković penetrated the building and took ambassador Vladimir Rolović (a former OZNA colonel[3]) hostage.

The men tied Rolović to a chair, pulled a leather belt around his neck and shot him in the face and stomach.

[7] Stojanov and the other two assailants, Marinko Lemo and Stanislav Miličević,[8] was sentenced in the same trial to between two and four years in prison and deportation.

[2] The Swedish police investigation in 1971 had failed to uncover that the kidnapping of Rolović was not the goal of the attack on the Yugoslav Embassy.

The Swedish-Croatian journalist Tonči Percan showed, after a thorough examination of the archive material in Stockholm 45 years later, and after talking with the mastermind behind the attack Ante Stojanov, that it really was an act of revenge.

Before Rolović was murdered, Barešić had placed a photo of Ilija Stanić on the ambassador's desk; It was a message to UDBA and Tito that revenge was completed.

It was hijacked in order to demand that the six Croats who were imprisoned for the murder of Yugoslav ambassador Rolović in Stockholm in 1971 be released.

[7] Three Croatian men, Tomislav Rebrina (36), Nicola Lisac (44) and Rudolf Prskalo (29),[8] from the fascist Ustaše movement held 86 passengers and 4 crew members hostage.

The hijackers and their comrades were arrested and received extremely symbolic punishments - rather protection - in Spain which was then under an authoritarian regime led by Francisco Franco.

[1] Again, he created headlines when he repeatedly hunger striked to get his life sentence timed and avoid solitary confinement.

In 1973, the much talked about terrorist law was passed, which gave the Swedish Security Service (Säpo) greater authority.

[1] Stojanov told an interviewer in 2004 that he considered the ambassador's murder and aircraft hijacking as the start of the Croatian struggle for independence.
