Salah Abdeslam
The 26-year-old French national, who was born in Brussels, was wounded and arrested during a police raid in the Molenbeek area of the city on 18 March.
Police had been hunting him since the 13 November attacks, warning members of the public not to approach him.
On 15 March, Abdeslam's fingerprints were found in a flat in the southern Brussels district of Forest. Belgian prosecutors told the BBC at the time that it was not clear when he had been there, because the fingerprints could not be dated.
