The Copenhagen police say the arrest of the two men, aged 22 and 27, bring to three the number of people in custody. A fourth suspect is being sought on an international arrest warrant. Investigator Brian Belling said in a statement Thursday that police are continuing their investigation, adding, "we are confident that the perpetrators will be brought to justice."
Police did not immediately link the Aug. 6 tax agency blast to another one, four days later, at a nearby police station, though they said industrial explosives were used in both. No one was injured in the police station explosion.
