Danish police arrested a young man on Friday and charged him with complicity in the shootings in Copenhagen in mid-February in which two people were killed and five police officers wounded.
Danish media reports described the man as personally connected with the gunman, Omar El-Hussein, who was shot dead by police following the second shooting at a synagogue in Copenhagen.
Dan Uzan, 37, a Jewish volunteer security guard, was killed in the synagogue attack. Movie director Finn Norgaard died in an earlier attack on a café.
Two other men were previously detained on charges of aiding Hussein.
Police had no further comments on the arrest.
State-owned DR TV reported that all three men charged with complicity in the shootings knew each other, and lived in the same neighborhood as Hussein.
A preliminary legal hearing for the newly arrested man is due to take place on Saturday.
