Belgian police released five people who had been detained in raids in connection to the terrorist attacks in Paris in November, the federal prosecutor's office said Monday.
During the raid on Sunday, police had searched a house in the center of Brussels and detained two brothers and a friend of the two brothers for questioning, the office had said in an earlier statement.
A second raid took place on Monday morning in the Brussels district of Laeken, leading to the detention of two more people, the statement said.
Police found no weapons or explosives during either of the raids.
Belgian police have been searching for Salah Abdeslam , a suspect in the Nov. 13 atrocity that left 130 people dead in the French capital, and have so far charged eight people in connection with the attacks.
