A manhunt is still ongoing in the Netherlands for the suspect in a tram shooting in Utrecht on Monday, the mayor said during a press conference.

Jan van Zaben said authorities are doing “everything possible to catch the suspect,” adding that the motive is “still unclear.”

Police say Gokmen Tanis, 37, who was born in Turkey, is wanted following the incident. They have asked locals to contact authorities immediately if they see him.

The threat level will remain at 5 – the highest – for the entire province until 10 p.m. local time tonight.
