BERLIN, June 26 (Xinhua) -- The suspect arrested in connection with the murder of German politician Walter Luebcke admitted that he had prepared and carried out the crime on his own, Federal Attorney General Peter Frank announced on Wednesday.
The murdered German politician Luebcke was found with a gunshot wound to his head in his garden at the beginning of June.
Around three weeks later, a 45-year-old man was arrested on suspicion of murder after a DNA trail led to a hit in a database of the German authorities.
The suspect, who has a long criminal record, is known to German authorities to have been in contact with extreme right-wing groups in Germany such as Combat 18.
German Minister for the Interior Horst Seehofer called the investigation a quick success but stressed that "this is not the end of the investigation of this political murder".
It was also a matter of identifying possible accomplices or confidants and the German interior minister called on citizens to distance themselves clearly from right-wing extremists
Germany needed a resolute response to the murder of the Kassel district president Walter Luebcke, president of the Bundestag Wolfgang Schaeuble demanded on Wednesday.
"The state's monopoly on power is there to be applied. Consistent and resounding," Schaeuble said during a speech in the German parliament.
If the German federal prosecutor's suspicions about the motives for the crime were confirmed, then "we are dealing with a frightening extent of right-wing extremist violence," Schaeuble stressed.
It was therefore "up to the constitutional state to quickly and comprehensively clarify the further background" and up to the politicians and the security authorities to prove Germany's democracy remained strong, the German parliamentary president added.
