HOUSTON – A rap video helped authorities in Houston identify 20 suspected gang members, all of whom are now facing gun charges after police said they brandished weapons while filming a music video in March.

According to a report from KSAT's sister station, Click2Houston, rappers Emekwanem Biosah Jr, known as Maxo Kreme, and Warren Brown, known as NFL Cartell Bo, were filming a rap video at Lakewood Park when police responded to the park.

Police told Click2Houston the video featured dozens of loaded guns, some stolen, and that some students being released from a nearby elementary school were also featured in the video.

While the firearms were being used as props, the people holding them are documented gang members, the Houston station reported. Most of the gun-toting extras ran, leaving the weapons behind, police told Click2Houston.

Brown, a convicted felon, was charged with illegally possessing two assault rifles and with threatening a police officer. He was released on bond and was ordered to wear an ankle monitor, but police told Click2Houston he cut it off and has been on the lam since.

Authorities said the video was uploaded to YouTube two months after it was filmed and that police used the video to track down and identify everyone in the video who was seen holding a weapon.
