A 47-year-old politician, from the Green Party, was attacked by two people while putting up election posters in the eastern German city of Dresden.
Shortly afterwards, police officers arrested a 24-year-old woman and a 34-year-old man as suspects, Dresden police said on Tuesday evening. A police spokesman did not initially identify the attackers.
The male attacker pushed the politician aggressively around 6:50 pm (1650 GMT), and insulted and threatened her, police said. He is also said to have torn down two election posters.
The 24-year-old woman reportedly joined in and spat at the politician, who was accompanied by volunteers and a film crew. The police confronted the two attackers in the immediate vicinity.
The 34-year-old man is being investigated for assault, threats, insults and damage to property. The 24-year-old woman is being investigated for assault.
Because the two had allegedly been standing with a group chanting Nazi slogans, they are also being investigated for using symbols of unconstitutional organizations. The suspects were not taken into custody, the police spokesman said.
