Najim Laachraoui, the suspected attacker in the Brussels Airport attack is reportedly held in the Anderlecht area. He was shown in the right in the CCTV image taken before the Zaventem airport attack, later released by police.
Local media has reported that, he had been arrested in the Anderlecht district of Brussels, adding that he was the third man pictured in CCTV footage alongside two suicide bombers who blew themselves up on Monday.
Earlier, two of the other attackers who blew themselves up in Brussels have been identified as brothers, Khalid and Brahim el-Bakraoui who were being sought for links with Salah Abdeslam, the prime suspect in the Paris attacks, RTBF television reported today, citing police sources.
Twin explosions at the airport and another at a metro station on Tuesday left about 34 dead and 250 wounded. Belgium is observing three days of national mourning.
The Islamic State (IS) has said it was behind the attacks and warned that more would follow.
Belgian police earlier Wednesday issued an appeal for information about the two men believed to have blown themselves up at the airport.
The police posted several tweets with the caption “Terrorism: who knows this man?”, showing CCTV close-ups of two men pushing trolleys with suitcases through the airport departure hall.
They gave three slightly different images for each of the two men who the federal prosecutor said Tuesday had likely blown them up in the attack.
A third man, dressed in a light coloured jacket and wearing a dark hat, who was shown with the two others in a CCTV grab issued Tuesday, is believed to have fled the scene and is now the subject of a massive manhunt
