BERLIN (Reuters) - German police arrested a 24-year-old Syrian refugee last Friday after receiving a tip that the man was planning a possible Islamic-motivated attack, state officials in North-Rhine Westphalia said on Tuesday.
"Investigations conducted thus far have found no evidence of a concrete threat," the state's interior ministry said in a statement.
The man, who was arrested in the neighbouring state of Rhineland-Palatinate, remains in police custody, according to the statement.
