A social media account on "Telegram" with content in the Serbian language has published several leaflets with content in the Serbian language distributed in the North, through which citizens are called to "target Kosovo police patrols, ignore the police when they speak to them and demolish official vehicles."
This account claims without evidence that "Kosovo security services" have printed and distributed leaflets in Cyrillic and with the name "People's Defense" under the Serbian flag, to appear convincing and cause confusion among Serbs.
After research conducted by hibrid.info, the Kosovo Police and the Serbian List have not released the claim that this act was committed by "Kosovo security services", as stated in the Telegram account's post.

The post of the account “BUNT je stanje duha”, translated into Albanian:
In the Serbian areas of Kosovo and Metohija, another provocation and prank attempt by the Kosovo security services is underway. Namely, since 19:00, leaflets with alleged instructions on how to treat members of the Kosovo police appeared in mailboxes and on the streets in Mitrovica, Kosovo, as well as in other municipalities. The notices are written in Cyrillic script, calling on citizens to target Kosovo police patrols, ignore the policeman when he speaks to them, and demolish official vehicles. It is clear that the leaflets were printed in Cyrillic and under the Serbian flag to appear convincing and cause confusion among Serbs. It is indicative that the controversial leaflets appeared exactly on the day when Serbs from a peaceful meeting in Mitrovica, Kosovo showed unity and told the international community that the decision to abolish the dinar means the end of life for the Serbian people.
All this is happening just one day after the Albanian service in Leposaviq, supported and accompanied by the Kosovo police, destroyed the graffiti, and on the day when Serbs showed their unity and determination to stay in Kosovo and Metohija with a grand rally.
Regarding these leaflets, the Serbian List, through its official Facebook page, has issued a statement calling on citizens not to fall for such provocations. (see here)
In the announcement of this political entity, at no point is there any allusion to the perpetrators of this act, and according to them, such actions, whoever committed them, are against peace and appear to have malicious intent for further destabilization.
In the 24-hour report issued by the Kosovo Police, the perpetrators are not identified and it is stated that the case is under investigation.

The account in question claims that these leaflets were distributed a day after the graffiti was cleared in the four northern municipalities of Kosovo, with a Serb majority.
Local media reported on February 11th about the appearance of graffiti in the North with the signature of the Northern Brigade with the inscription “When the army returns to Kosovo, the Northern Brigade lives”. (see here and here)
Analyze:
Linking the February 11 incident of graffiti displayed in four Serb-majority municipalities in northern Kosovo, a Serbian-language Telegram account claims without evidence that Kosovo security services have distributed leaflets in the North, calling on citizens to “target Kosovo police patrols, ignore the police when they speak to them, and demolish official vehicles.”
Hibrid.info has not found any information from credible sources that such an act was committed by, as it is said, "Kosovo's security services".
Based on the working methodology, hibrid.info evaluates this claim as a "Conspiracy Theory".
Reasoning:
"Conspiracy theories" are considered to be informational content that contains a false or unverifiable description of a phenomenon, event or person, presenting it as part or the result of a secret plan ("conspiracy"). The characteristic of these contents is that they present a series of claims, presented as facts, between which cause-effect relationships are established, without providing any reliable evidence.
