Belgian police have confirmed that Mohamed Abrini, wanted over last November's terrorist attacks in Paris, has been arrested in Brussels.
Police have also said Mr Abrini was arrested along with four other people, including a man they believe may have helped the bombers behind the attack in Brussels Airport on 22 March.
Mr Abrini, a 31-year-old Belgian, has been on Europe's most wanted list since being seen on a motorway service station CCTV video driving with another Paris attacks suspect, Salah Abdeslam, towards Paris from Belgium.
The car they drove was used two days later in the 13 November attacks, in which Abdeslam's elder brother was a suicide bomber.
Speaking at a news conference, Belgian Federal Prosecutor Eric Van der Sypt said investigators are verifying whether Mr Abrini could be positively identified as the third person present during the attacks on Zaventum Airport in Brussels, the so-called 'man with the hat'.

Mr Van der Sypt also said that Osama K, also known by the alias Naim al-Hamed, and a second person, named by prosecutors as Hervé BM, were arrested in Brussels in connection with the attacks on the city last month.
He said investigators were veryifying whether Osama K could be positively identified as being the second person present at the time of the attack on the Maelbeek metro station in Brussels last month.
Mr Van der Sypt said this second person had been filmed at a Brussels shopping mall buying bags which were used later in the attacks on Zaventum Airport.
Two other people, not named by the prosecutor, were also arrested.
The arrests took place in the Anderlecht district of Brussels, home to several other Paris attack suspects.
The "man in the hat" left the airport shortly after the twin suicide bombing and was tracked on CCTV for several kilometres into the city centre.
Yesterday investigators released new video footage of him and urged people to look for his discarded coat.
Wearing glasses and a hat, he had been very difficult to identify from the footage showing him pushing a laden luggage trolley alongside the two men who would blow themselves up with similar explosive bags. A third bomb was later found abandoned at the airport.
Mr Abdeslam was arrested in Brussels two weeks ago, four days before so-called Islamic State suicide bombers struck in the city.
