Belgian police released three people Friday who were detained overnight in a counterterror operation in the Brussels area, Sputnik reported.
Searches were conducted in homes of people under scrutiny on suspicion of links to terrorism and foreign fighters returning from Syria, the RTBF broadcaster reported, saying no weapons or explosives had been found.
Two women and a man, who was tagged electronically for trying to leave for Syria, were released after being questioned by the investigating judge, according to the broadcaster.
Belgium has been investigating several cases related to last year’s terror attacks in Paris and this spring's Brussels bombings, as well as foiled terror plots in the country.
