A man has been arrested following a shooting on a tram in the Dutch city of Utrecht which left three people dead, police say.

Five others were injured in the incident, and authorities say the attacker’s motive remains unclear.

Gokmen Tanis, a 37-year-old Turkish man, was detained several hours after the attack. It is not yet clear where he was arrested.

The incident sparked a city-wide manhunt and the closure of schools.

One witness told local media that “a man started shooting wildly”.

Several of the injured are in a critical condition.

Another witness told Dutch public broadcaster NOS that he had helped an injured woman when the tram came to an emergency stop.
