Brussels bomb suspect, Najim Laachraoui arrested: Belgian newspaper

Najim Laachraoui is regarded as chief bomb maker of ISIS

A prime suspect in Tuesday's Brussels bombings, Najim Laachraoui, was arrested on Wednesday in the city's Anderlecht district, Belgian newspaper DH said on its website.

Police were hunting him as a man seen with suspected suicide bombers at Brussels airport. The suicide bombers were named as Khalid and Brahim El Bakraoui.

The two men who blew themselves up at Brussels airport on Tuesday were brothers known to the police and a third attacker, who is at large, is a known Paris attacks suspect, Belgian media said on Wednesday.

Federal prosecutors declined to comment, but said they would provide information in the course of the morning.

Laachraoui's DNA had been found in houses used by the Paris attackers last year, prosecutors said on Monday, adding that he had traveled to Hungary in September with Paris attacks prime suspect Salah Abdeslam.

Captured on a security camera photograph at Brussels Airport on Tuesday morning beside the El Bakraoui brothers, Laachraoui did not detonate a bomb and is still at large. A bomb was subsequently destroyed in a controlled explosion.
