An internal affairs investigation has been launched by Danbury Police into a disturbance complaint Wednesday at Danbury Library. 

A library security guard is seen asking a person to leave because he was taking video, which is against library policy.  The man says he's working on a story and exercising his First Amendment rights.  Danbury Police were then called to respond.

The man refuses to show police his ID and was told that he could be arrested for trespassing.  Eventually, the man provided ID and left, being told the citation would be sent in the mail. 

Chief Patrick Ridenhour says it's fortunate that there were no arrests or injuries, but he is concerned about how the incident was handled by the responding officers and supervisor.  The Internal Affairs Division will review any applicable laws, analysis of the video as well as footage from recently purchased body cameras.

Once the investigation is complete, Ridenhour says they will take the appropriate action based on the findings.
