AMSTERDAM, May 7 (Reuters) - An explosion damaged the headquarters of the largest party in the Dutch parliament, D66, on Thursday evening, local police said, adding there were no injuries.
Police said a suspect had been arrested following the explosion, which happened at the party office in the centre of The Hague shortly after 9 p.m. local time (1900 GMT).
Dutch Prime Minister Rob Jetten, who is also the leader of D66, said a bomb made of fireworks had been thrown through the letterbox in the frontdoor of the building in what he described as "a cowardly act of intimidation."
The centrist, pro-EU D66 party last year won the election in the Netherlands in a surprise victory over the far right Freedom Party led by nationalist Geert Wilders.
Its head office was also damaged during an anti-immigration protest last year, when protesters smashed the windows of the party seen by many on the far right as serving a progressive elite.
