A CAR ploughed into a trade union demonstration in Munich today, seriously hurting 28 people including a child.

The car’s driver overtook a police car following the demo by the Ver.di public service union, and then drove into the rear of the demonstration, running over trade unionists marching as part of a one-day strike by childcare workers demanding better wages.

The driver, who has been arrested, was an Afghan asylum-seeker, police said — further inflaming an election campaign in which most parties have demanded crackdowns on immigrants. While police believe the attack was deliberate, the motive is not yet known.
