DOWNEY -- Video of a multiple person fight outside of Buffalo Wild Wings surfaced Sunday afternoon.
The cellphone footage, posted on Facebook by Dave Amaro, showed multiple individuals trading blows outside of the popular chicken wing restaurant, located at 193 Stonewood Street within the Stonewood Shopping Center.
Many of those involved can be seen wearing either blue jerseys similar to those worn by the Buffalo Bills, or red sports attire similar to that of the San Francisco 49ers. Both teams played Sunday and lost their games to the New England Patriots and Pittsburgh Steelers, respectively.
The video was posted somewhere around 2 to 3 p.m.
According to comments attached to the video by the original poster, problems began inside the restaurant when some alleged 49ers fans started becoming aggressive with a Steelers fan, who walked away. However the situation continued to escalate.
“The rude 49ers fans started talking (expletive) to everyone. They messed with the wrong group when they went outside and got beat up,” the post said.
According to the original Facebook post, a man wearing red seen at the nine second mark is attributed with starting the entire episode.
In a statement Monday, the Downey Police Department said officers were dispatched to the restaurant at about 1:20 p.m. after receiving a call of two men fighting.
"When the officers arrived, the scene was calm, although one man claimed to have been involved in an earlier fight with another group of men who had already left the scene," the statement said. "He did not want to pursue any criminal charges at the time, but later came to the Downey Police Station and filed an assault report.
"Later in the same afternoon, the police department was made aware that a video depicting the fight had been posted on social media. In the video, it was apparent more than just two men were involved in the fight. So far, only moderate injuries have been reported from this incident.
"The Downey Police Department takes such matters seriously and will diligently work to identify and prosecute those involved."
Mayor Luis Marquez and Mayor Pro Tem Alex Saab said the fighting depicted in the video isn't indicative of Downey's values.
"As a local resident and parent, I was appalled at the behavior I witnessed in the video footage from this weekend, but I am confident that Downey Police will complete a thorough investigation and justice will be served," Marquez said. "We in Downey are proud of our thriving business districts and safe neighborhoods, and we want to reassure both visitors and residents that this isolated incident is being taken seriously."
"Fortunately, the inappropriate behavior captured on video outside of a local restaurant this weekend was an isolated incident and not representative of our residents' values," added Saab. "I look forward to meeting personally with our Police Chief regarding the Department's investigation and response in order to ensure the safety of all of our residents and visitors."
Buffalo Wild Wings declined to comment.
