Police recently found DNA, of a recently identified suspect, on explosives used in last year’s Paris attacks, a French source said; however, Belgium’s prosecutor stated that they are “far from solving the puzzle” of the killings.
"We have not a bad amount of pieces of the puzzle and in the last few days several pieces have found their place," Belgian Federal Prosecutor Frederic Van Leeuw told a news conference in Brussels.
"But... we are still, far from solving the puzzle."
The prime suspect in the attacks, Salah Abdeslam, was arrested in Brussels on Friday, following a four-month-long chase.
Investigators in Belgian identified the suspected accomplice in the Paris attacks as Najim Laachroaoui, who also used the alias Soufiane Kayal.
In September, Laachroaoui used the alias to travel to Hungary with Abdeslam, who is the last known survivor, out of the 10 suspects, to carry out the shootings and suicide bombing that left 130 people dead in the French capital.
DNA evidence, from the suspect, comes from explosives used in the gun and suicide attacks in Paris, a source close to the French investigation reported.
Two detonators and a large cache of weapons were found in the apartment that Abdeslam is thought to have fled during a raid last week, prosecutors told Belga news agency.
