DENVER — The controversy sparked by Broncos linebacker Brandon Marshall’s decision to take a knee during the national anthem is leading to questions about his allegations of police  excessive force, misconduct and cover-up.

On Tuesday, Marshall revealed for the first time when and where the incident occurred.

Through a spokeswoman, Marshall said it happened on July 4 at the Bayside Marketplace in Miami. News accounts showed chaos erupted there after reports of gunshots at a fireworks show.

In an op-ed piece in the Denver Post last week, Marshall said he was at a restaurant with three other people. He said when they tried to leave, five officers rushed toward him to take him down.

He said the officers handcuffed him and he heard one say they were taking him in for resistance.

Marshall said he was in the back of the police car heading toward the station when one of the officers radioed in and said to bring him back. They told him they would not take him in “as long as you keep this between us.”

The Miami Police Department said the scenario Marshall described would be a violation of protocol, but it has no records of it happening.

The department said it does not have any reports on an arrest or contact with Marshall.

When asked if Marshall had any plans to file a complaint or internal affairs report with Miami police, the spokeswoman referred us to him or his agent.  Neither have responded for comment.

A spokesman for the Broncos said they do not have any information about the alleged incident and also referred questions to Marshall.
