Explosion near West Jutland school likely caused by two acid bombs

A small explosion at the sports fields beside Janderup School in Varde Municipality was probably caused by two acid bombs, police said.

South and South Jutland Police received the report on Monday afternoon. Subsequent investigations indicated that the explosion likely came from two devices made with chemicals that had reacted inside containers.

The fire incident commander washed down the area, so there was no remaining danger of acid injuries. Police collected and removed the material that made up the suspected acid bombs and are now seeking witnesses.

The case follows a similar incident last week, when Central and West Zealand Police responded to a report of an acid bomb detonated at a sports field near Rynkevang School in Kalundborg. A police inspector said five teenage boys had set it off because they were bored. The boys were questioned on Tuesday in the presence of their parents and social authorities, and later charged with violating Denmark's weapons law.

Acid bombs are made by mixing different chemicals. The resulting reaction increases pressure until the container, typically a bottle, explodes. The police inspector warned that children can suffer serious injuries if they come into contact with the chemicals.
