Tanis is being held on suspicion of manslaughter with a possible terrorist intent, though the investigation is currently underway and other possible motives are being considered.
The day before, the Turkish agency Anadolu reported, citing Tanis' relatives that the suspect had fired at his relatives over "family matters".
According to Dutch media, Tanis has already had legal problems. Thus, according to the newspaper Algemeen Dagblad, Tanis had been summoned to court on 4 March in connection with rape accusations, including sexually assaulting his victim several times, and threatening to burn down her home.
In 2013, the Turkish-born suspect was suspected of attempted manslaughter by "opening fire on a flat".
Furthermore, in recent years the man had been accused of committing burglary, shoplifting, drink-driving, and assaulting a police officer.
