A Turkish man has been arrested following a shooting in the central Dutch city of Utrecht which left three people dead, police say, the BBC reports.
Five others were injured in the incident, which the authorities say appears to be a terrorist attack.
Police have identified the man as Gokmen Tanis, 37.
It is not yet clear where Mr Tanis was detained.
A photograph of him was posted on social media by police, who warned people against approaching him.
A number of raids were reportedly carried out and counter-terrorism officers were pictured surrounding a building near the 24 Oktoberplein junction, where the tram attack took place.
The tram attack happened at about 10:45 local time (09:45 GMT).
