(CNN) The New England Patriots are once again embroiled in controversy.

This time, they've been accused of recording the Cincinnati Bengals sideline during the team's game against the Cleveland Browns Sunday. ESPN was first to report on the story. The Bengals are due to play the Patriots Sunday.

"We are aware of the incident, and we are aware it is being investigated by NFL Security," the Bengals said in a statement to CNN Sports. "We will have no further comment."

The Patriots organization released a statement saying its video team was shooting a behind-the-scenes feature on the Patriots scouting staff at FirstEnergy Stadium for a series called " Do Your Job ."

The team said it acknowledges that the production crew "unknowingly violated a league policy by filming the field and sideline from the press box."
