@coldjoint,
The Public Prosecutor General of the Federal Court of Justice has taken over the investigation - because of the special significance of the case.
The man arrested at the weekend under urgent suspicion is a 45-year-old man who, at least in the past, had clear connections to the right-wing extremist scene and is said to have been active in the vicinity of the Hessian NPD [a still legal neo-Nazi party].
Ten years ago he was also arrested by the police in Dortmund together with almost 400 Autonomous Nationalists. The right-wing radicals had attacked a rally of the German Federation of Trade Unions (DBG) on 1 May, and the man now in the Lübcke case was one of the accused at the time. He was sentenced to seven months probation for breach of the peace.
According to information spiegel-magazine got, the murder suspect has attracted attention several times in the past for violent offences, violations of the weapons law, property and other criminal offences.
It is not yet known whether he was convicted in these cases.
(The name of the suspect is known to SPIEGEL. In order not to jeopardise investigations for possible supporters or confidants, the editorial staff has decided, at the request of the investigators, not to publish him in abridged form for the time being.)
