Almost a dozen notes threatening a new terrorist attack have been found in the same Copenhagen district where a gunman opened fire on a debate on free speech in February, police have said.

As reported by Danish news website TV2 Lorry, eleven notes have been discovered around the district of Østerbro warning of a new terror attack.

They apparently said: “Denmark will soon be hit by a terror attack that will make what happened on February 14 look like a prank – look forward to it.”

A number of the notes are said to have been placed at Krudttønden, the café in Østerbro where gunman Omar El-Hussein opened fire on a talk on free speech and blasphemy, killing 55-year old filmmaker Finn Nørgaard.

El-Hussein, 22, later killed security guard Dan Uzan, a security guard at a Copenhagen synagogue. Several police officers were injured in the shootings before El-Hussein was killed by police.

The notes, say TV2 Lorry, were further placed at a memorial site for Nørgaard.

Speaking to news agency Ritzau, Copenhagen Police Spokesman Carsten Reenberg said: “Some notes have been hung up in Østerbro. I can’t discuss the content but we are investigating it.”

TV2 Lorry said that police have enlisted the help of Danish Security and Intelligence services to help track who had been responsible for the placing of the letters.

Five men have been arrested for allegedly aiding El-Hussein, a Dane of Palestinian origin, in getting hold of the weapons he used in the twin attacks.

Last month all five had their custody extended for an additional four weeks.

The original attack was inspired by the massacre of Charlie Hebdo staff in Paris that took place in January, police said.
