The alarm came in just after 1pm on Monday afternoon after a bottle of unknown content slammed into the school's main staircase. The school is evacuated, according to police.
- Yes, we are still on site. Someone has thrown a bottle-like object through a window pane and you have heard a bang, says Patric Fors at the police's command center to TT.
The National Bomb Guard is on its way to the site to check that there is nothing dangerous left.
According to the police, it is a minor blow, and no one should have been seriously injured.
- However, a few people should have breathed in smoke, says Patric Fors.
Rönnowska is a high school with vocational programs.
