A 23-year-old Dutch national has been arrested in Belgium because he was involved in ‘concrete preparations’ for terror attacks, RTL reported on Friday.

The man is said to come from the village of Clinge in the southern province of Zeeland.

‘It was a question of days,’ the spokesman said. ‘We had information that the threats were very concrete. The man was working out the practicalities.’

The man was arrested in a café on Wednesday evening where he was apparently trying to persuade people to join his cause.

His alleged targets included Belgian broadcaster VRT and ‘several political institutions’. The man appeared to be working alone, the spokesman said. He is due to appear in court on Tuesday.
