The Third Basic Prosecutor’s Office confirmed to N1 on Thursday it ordered the 30-day detention to a 70-year-old man from the northern town of Nova Pazova suspected of threatening N1 Belgrade journalists and their families.

The man identified only by S.C. initials sent a letter to N1 Belgrade office, saying the television building would be blown up and its reporters’ might lose their family members.

He was arrested within 24 hours after N1 reported the threat to the police.

The man signed the letter as “Belgrade veterans from 1999 wars”, but the president of the Serb War Veterans association denied the group had anything to do with the letter.

The threats followed the regime’s hints that N1 “recognised Kosovo’s independence, ” by showing it separately from Serbia in the weather forecast report, which was proved not to be the case.

N1 refers to Kosovo in line with UN Resolution 1244 form 1999, which is neutral regarding Serbia's ex-province final status.

On Tuesday, journalists’ associations, some opposition parties, and OSCE condemned the attack, calling for an immediate investigation.

  Serbia’s Ministry of Culture and Information also condemned the letter, saying dialogue with fists and use of force were far behind us.

Later, Serbia's Prime Minister Ana Brnabic did the same, but after being asked to comment.

Zorana Mihajlovic, Deputy Prime Minister and an official of the ruling Serbian Progressive Party (SNS) led by President Aleksandar Vucic, said such attacks were inadmissible in any democratic society.

The Justice Minister Nela Kuburovic joined in condemnation.
