An explosion has hit crime laboratories in a Brussels suburb in what police officials are treating as a criminal but not terrorist incident.
Shortly before 02:30 local time (00:30 GMT), a car rammed through three fences, leading to an explosion and a large fire, RTL Belgium reported.
Belgian media said “one or more” suspects then reportedly set off a bomb near the laboratories.
But police could not confirm that a bomb had exploded.
Belgium’s terror alert level remains high since bomb attacks on Brussels airport and the city’s metro, claimed by so-called Islamic State, killed 32 people in March, the BBC reports.
There were no casualties in the latest blast, Belgian media said, and it is unclear what happened to the perpetrators.
Fire service spokesman, Pierre Meys told Agence France-Presse that the “extremely powerful” blast “was probably not accidental.”
Some 30 firefighters helped put out the resulting fire at the National Institute of Criminology, which media said suffered “significant” damage.
Prosecutors said an investigation was now under way.
