A heartbreaking goodbye quickly descended into chaos after police stormed a funeral in North Carolina, arresting the wrong man in front of shocked mourners.

As friends and relatives stood mourning Kabem Smith, a beloved father and community member, officers from the Lee County Sheriff's Office swooped in, targeting what they believed was a breakthrough in a 30-year-old cold case.

But, their so-called 'suspect' turned out to be Smith's brother - an innocent man simply saying goodbye to his loved one.

'It was the most unreal thing I have ever seen,' family friend Bryant McKinney told WRAL.

The man officers detained bore a striking resemblance to Willard Eugene Smith, who has been on the run for decades in connection with the 1995 murder of Rodney Cotten.
