The authorities in Germany have warned the country is facing the threat of terror attack after an arrest over an alleged plot to blow up two trains.
The head of the federal crime office, Joerg Ziercke, said the hunt was on for a second suspect and the danger was "still out there".
Investigators first thought the bombs were part of a blackmail attempt but they now believe the incident was the work of a terrorist group based in Germany.
A note written in Arabic, a telephone number in Lebanon, and packets of starch with labels in Arabic and English were found alongside the devices.
The authorities say they are investigating a possible link to Lebanon, but they also have not ruled out a link to Pakistan.
The identical suitcase bombs were fitted with timers set to go off 10 minutes before the trains arrived in Dortmund and Koblenz.
Police think they failed to detonate because of a construction flaw.
