- Suspect accused of supplying weapons used in January 2015 attack in Paris
- Amedy Coulibaly killed four at kosher supermarket before police shot him dead
- Two others arrested in Spain on suspicion of arms trafficking, officials say
The man, named as Antoine Denive, 27, was arrested in Malaga, Spain, in a joint operation by French and Spanish authorities, officials said Wednesday.
Two other people -- one from Montenegro and one from Serbia -- were arrested in Tuesday's operation, officials said. They were arrested on suspicion of arms trafficking, officials said.
Denive was said by authorities to be from the northern French city of Calais.
Police said Denive left France after last year's attacks and stayed in Malaga, on the Mediterranean coast, where he continued his illegal activities using false identification documents.
Coulibaly killed four hostages in the supermarket before police shot him dead.
His attack followed one on the offices of the French satirical magazine Charlie Hebdo.
