Germans nab terror suspect from Tunisia

German police have arrested a Tunisian man after discovering “toxic substances” at his flat in Cologne, officials said on Wednesday, with prosecutors not ruling out a possible terror motive. The man was detained on Tuesday night after officers raided his flat and came across “unknown substances” that are being analysed by specialists, Cologne police said in a statement. The suspect’s wife was also taken in for questioning but is believed to have since been released.
