OMAHA, Neb. (AP) — Two Omaha men who were formerly rival gang members have joined together to show their commitment against violence at a local Black Lives Matter protest.

At the protest Friday, Travis Bennett, a former Bloods gang member, gripped a red bandanna. Markail Channel, a former Crips gang member, held the blue bandanna. The men tied the garments together as a sign of harmony.

Multiple photos of the men emerged on social media, two of which have been liked or shared tens of thousands of times. Omaha Police Lt. Ken Kanger of the department’s gang unit also took a photo with the men.

Bennett and Channel were on the brink of fighting five years ago when their Millard South High School principal made them resolve their conflict through dialogue. The men now call themselves brothers.
