Three former members of the disbanded leftist Red Army Faction terrorist group who remain at large have reportedly been linked to a botched armored car robbery near Bremen last summer.

The NDR public broadcaster first reported that DNA matching that of Daniela Klette, Ernst-Volker Wilhelm Staub and Burkhard Garweg was found in the getaway cars used in the June 6 crime.

Investigators weren't immediately available for comment but police confirmed the details to the dpa news agency Tuesday.

In the robbery, three masked assailants blocked the armored car in a parking lot, then one opened fire on the vehicle but they were unable to get inside.

NDR reports that DNA evidence also linked Klette and Staub to a similar armored-car robbery in 1999.
