CHARLOTTE, N.C. -- For the first time, Charlotte-Mecklenburg Police are revealing how its detectives were able to arrest 31 people for contributing to rioting in the days following the death of Keith Lamont Scott.

Detective Josh Gibson was one of the detectives who pieced together video from surveillance cameras, social media and TV reports to make cases.

One of the arrests was a Calvin Howell.

Working off a still photo from a surveillance camera, Detective Gibson looked for videos of men with similar clothes.

He said he soon found a news report that aired on NBC featuring an interview with Howell wearing the same clothes.

Using those videos and an online criminal record, Detective Gibson said he was able to make a positive identification.

He said they're still looking for at least 10 more people, but he knows not everyone responsible for the riots will be caught.
