A suspect being sought in the terrorist attack on the Brussels airport is still on the run, Belgian federal prosecutor Frederic Van Leeuw says, contradicting earlier media reports.

Prosecutor Leeuw said that investigators have found 15 kilograms of TATP explosives at the house which the suspects in the Brussels attack left from for the airport. The explosives were the same type of explosives used in the Paris attack.

Leeuw also said that a cab driver who drove the three suspects to the airport led authorities to the house in Brussels. A special squad found the explosives inside the house, along with other chemicals that are commonly used to make bombs.One of the suicide bomber has been identified through his fingerprints as Brahim El Bakraoui, a 29-year-old Belgian national. A second suicide bomber still has to be identified, Van Leeuw says."The third suspect, wearing a light-coloured jacket and a hat, is on the run," he adds. "He dropped off a big bag, then left before the explosions."

Belgian media earlier on Wednesday reported that Najim Laachraoui, the third main suspect in the Brussels terror attack, was arrested. But Belgian media later withdrew the claims.

Najim Laachraoui's DNA was found on explosives used in the Paris attacks, as well as at an apartment in Brussels where bomb-making equipment and one of Abdeslam's fingerprints had been found in December.

Belgium's chief prosecutor says investigators have found 15 kilograms (33 pounds) of TATP explosives at the house which the suspects in the Brussels attacks left from for the airport. FederalExplosions on Tuesday at the Brussels airport and a city subway center killed 34 people, including three suicide bombers, and wounded over 270 people.
