(Undated) -- Black Friday deal seekers at Walmart are kicking off the holiday shopping season with chaos and arrests. A melee over Blu-ray players at the big box retailer near Fort Worth, Texas led to an overturned display case and at least one injury. A video of the wild fight surfaced on YouTube. A dozen picketers at another Texas Walmart are behind bars for blocking crosswalks during a protest against the store's low wages. Police took around ten protesters into custody at an Ontario, California location for failure to disperse. The rally of Walmart employees was at least 150 strong, with another demonstration planned in Los Angeles.
