German prosecutors in the southern city of Stuttgart confirmed the arrest of a 34-year-old man on Friday suspected of engaging in arms dealing online, but did not confirm if the man had in fact supplied four guns to the Paris attackers or not.
"I can confirm that a man is in custody on suspicion of arms trading," a spokesman for the prosecutor in the state of Baden-Wuerttemberg told Reuters, adding that the arrest had been made on Tuesday.
In addition, German newspaper Bild reported the incident early on Friday, saying the arrested suspect has sold four weapons to the militants who killed 130 people in Paris on November 13.
Four emails were found on the man's smartphone, indicating that he was in touch with an "Arab in Paris", the newspaper Bild wrote, adding that the French prosecutors believe the weapons were used in the Paris attacks.
The four weapons were two AK-47s made in China and two Zasatva M70s made in the former Yugoslavia, sold online by the arrested suspect on November 7 to a buyer of "Arab descent."
Following the deadly attacks in Paris France declared a three-month national state of emergency and stepped up its air campaign against DAESH in Syria.
