More than 200 people were arrested in Washington Friday as some anti-Trump protests turned violent.
Cameras caught a limousine after it was set on fire.
Officers began using pepper spray and stun grenades to subdue protesters who they say were damaging cars and destroying property.
Police say it started about an hour before Trump was sworn in.
At least two officers were injured, and some police cars were damaged.
Protesters voiced their concerns over Trump's proposed policies toward immigration and health care.
Earlier in the day, several peaceful demonstrations took place at security checkpoints near the inauguration ceremony.
