Four terrorism suspects arrested in Rotterdam

The police arrested four men in Rotterdam on Sunday evening on suspicion of involvement in terrorism, the Public Prosecutor said in a statement on Tuesday. The suspects are three Dutch men and one Swedish man.

A foreign police service informed the Dutch authorities about the 29-year-old Swede's possible involvement in terrorism. He arrived in the Netherlands on a plane from Stockholm on Sunday afternoon. The police kept an eye on him, and arrested him with the three Dutch men early in the evening. 

After the arrests, four addresses in Vlaardingen, Delft, and Gouda were searched. No weapons or explosives were found. But the police did seize a number of data carriers for further investigation.

"There is also no concrete information that points to an attack", the Prosecutor said. "In the prevention of a terrorist attack, the Public Prosecutor and the police do not take any risks. Any indication may be sufficient for intervention."

The Dutch suspects are a 21-year-old man from Vlaardingen, a 30-year-old man from Delft, and a 23-year-old from Gouda. All four suspects are in custody for questioning and further investigation.
