UTRECHT, Netherlands (AP) Dutch prosecutors said Tuesday they are taking very seriously the possibility that the deadly shooting on a tram in the central city of Utrecht was an act of terror.

The nature of the Mondays attack and a note found in a suspected getaway car suggest a possible terror motive, prosecutors said in a statement, but they add that other possible motives also are being investigated.

They did not elaborate on what was written in the note found in the car.

The statement also said that investigations so far have not established any relationship at all between the main suspect, Gokmen Tanis, and the shooting victims.
