All four secondary schools at Het Hooghuis in Oss were evacuated late Monday morning after a bomb threat. The students from those four schools have been sent home.
The police say they are currently present at two of the four schools to investigate.
No one is allowed into the schools. The four secondary schools belong to the Hooghuis Lyceum. There is also a secondary school of the Maasland College in Oss. That school is still open.
