At least four cars were in flames in Västra Frölunda late Tuesday night, while police and emergency crews faced stone-throwing young people who also pointed green lasers at officers who attempted to deal with the situation.

“My girlfriend saw several young people throw a Molotov cocktail at a car,” one eyewitness told the Aftonbladet newspaper.

Later in the evening, police also received a call that a small cabin and several cars were burning in nearby Hisingen, the newspaper reported.

“One person has been taken to hospital; he had a minor injury to his leg. We don’t know how he got the injury,” Lars Tunefjord of the Gothenburg police told the TT news agency.

Two tram cars were also damaged by rock-throwers during the episode and small fires were also set at an area school.

Two young men were arrested later in the evening on suspicion of aggravated vandalism and were set to be questioned overnight.

According to police, five cars were totally destroyed on Tuesday night, while several more were damaged.

The incident follows a wave of car fires which took place in Västra Frölunda on Monday light.
