Belgian police arrested a man with a machete in the eastern city of Liege, broadcaster VRT reported on Sunday (Aug 7).
The arrest came the day after a machete-wielding assailant attacked and injured two female police officers in the southern city of Charleroi before being shot dead by another officer, in what the prime minister has said appeared to be a terrorist act.
VRT said Liege police received a call in the early hours of Sunday, and cordoned off an area before arresting the man. It said he was of Turkish origin, did not use the machete and was not previously known to the police.
The Islamic State group (IS) claimed responsibility on Sunday for the attack, saying the machete-wielding assailant was a "soldier" of the group.
Quoting an unidentified source, the IS-linked Amaq Agency said Saturday's attack came "in response to calls to target citizens" belonging to countries in a US-led coalition bombing IS in Syria and Iraq.
The assailant died on Saturday after being shot by officers. Police said on Sunday he was a 33-year-old Algerian with the initials K.B.
Belgium on Sunday opened a terrorism probe into the attack, the latest in a string of extremist assaults in Europe.
"We have been informed by federal prosecutors that an investigation has started for attempted terrorist murder... given certain elements (in the case)," Prime Minister Charles Michel told reporters.
Mr Michel, who saluted the courage of the police victims, was referring to the attacker's cry of "Allahu Akbar" (God is greatest) during the assault in front of a police station.
Police spokesman David Quinaux told broadcaster RTL-TVI the assailant had "taken a machete out of a sports bag he was carrying and dealt very violent blows to the faces of the two policewomen".
Belgium has been on high alert since suicide bombers struck Brussels airport and a metro station near the European Union's institutions on March 22, killing 32 people.
Those attacks were claimed by IS, which controls large areas of territory in Iraq and Syria and has claimed numerous terror strikes in Europe over the past year.
