Paris Attack Suspect's Fingerprints Found in Raided Belgian Apartment

— -- The fingerprints of one of the suspects from the deadly Paris attacks who remains at large were found in a Belgian apartment that was raided earlier this week, according to government officials.

Fingerprints belonging to Salah Abdeslam, viewed by Europol as the most wanted man in Europe, were found Tuesday inside the apartment in the suburbs of Brussels, but it is unclear exactly what that discovery means for the investigation.

Belgian Federal Prosecutor Eric Van der Sypt confirmed the presence of the fingerprints to ABC News, but said it was impossible to know how recent the fingerprints were, saying "they could be days -- or even weeks -- old."

Van der Sypt would not comment further on where the fingerprints were found in the apartment, whether personal effects belonging to Abdeslam were found there and when asked whether Abdeslam is thought to be one of the two men who ran away after a shootout at the apartment.

"It is a hypothesis but nothing more," he said.

Van der Sypt also wouldn’t comment on whether authorities are closer to catching Abdeslam.

In an emailed statement, the Federal Prosecutor’s office said “the investigation continues day and night."

Four Belgian police officers were wounded in the raid after they came under fire from a man wielding a Kalashnikov rifle inside the apartment, authorities said, noting that man was killed in the raid.

The man who was killed in the raid was identified as an Algerian national, Belkaid Mohamed, 34, who was in the country illegally and was unknown to authorities, except for a case of theft in 2014, according to the Federal Prosecutor’s office.

Two people who were “probably present in the flat as well and of whom the identity is as yet unknown, fled the scene,” the Federal Prosecutor’s office said.
