Dutch police have raided private homes and business premises in Amsterdam, Utrecht and The Hague and arrested 12 people in their search for the people behind last year’s attack on the Telegraaf newspaper offices, the paper said on Monday.

The 12 men who have been arrested are aged 20 to 27 and also face charges of stealing and fencing fast cars used in several ‘serious crimes’, the paper said.

No one was injured in the attack on the newspaper’s offices in Amsterdam last June, in which a van drove into the building at around 4am and then burst into flames.

Police suspect the attack was the work of the Netherlands’ most wanted criminal, Ridouan Taghi, who is also thought to be behind several gangland killings.

The public prosecution department has issued a reward of €100,000 for information leading to Taghi’s arrest.
