When we first heard this story, we didn’t think it was real.

A television production team that was in Washington to record a segment for “The Late Show With Stephen Colbert” was “detained” Thursday night in a House of Representatives building, according to a spokeswoman for the show.

Seven people were charged after a disturbance was reported Thursday night at the Longworth House Office Building, the U.S. Capitol Police said Friday in a statement.

The police statement gave no names or affiliations, and the police public information office declined to give details beyond what was in the statement.

According to the statement, officers saw seven people in a sixth-floor hallway at a time when the building was closed to visitors.

The people were part of a group that had been directed by police to leave the building earlier in the day, the statement said.

They were charged with unlawful entry, according to the police statement.

A statement from CBS said: “Triumph the Insult Comic Dog was on-site at the Capitol Wednesday and Thursday with a production team to record interviews for a comedy segment” on behalf of “The Late Show with Stephen Colbert.”

The spokeswoman said the group’s interviews were authorized and had been arranged through aides to the members of Congress interviewed.

After leaving an office on the day’s last interview, the spokeswoman said, the production team “stayed to film stand-ups and other final comedy elements in the halls when they were detained” by officers of the Capitol Police.
