Panthers spokesman Steven Drummond said in an email that authorities arrested four people in the incident.

The two protesters, Erica Madrid and John Nicholson, dangled over fans in the lower bowl and in front of press-box windows late in the third quarter, then displayed a banner telling the Charlotte-based financial institution to "dump Dominion."

The banner also included a website address, which outlined opposition to Bank of America's role in financing a liquefied natural gas export facility by energy company Dominion Resources in Cove Point, Maryland. Bank of America owns naming rights to the Panthers' home stadium.

The protesters dangled by ropes well into the fourth quarter.

The activists from "We Are Cove Point" said they are protesting "Bank of America's role in financing the planned liquefied natural gas export facility in Cove Point, Maryland."

Drummond says the team and the Charlotte-Mecklenburg Police Department are investigating the incident.

Both Madrid and Nicholson as well as David Baghdadi and Angela Vogel were charged with second-degree trespassing and resisting an officer.
