An investigation is underway near Kickapoo Casino in Harrah following a shootout between two rival motorcycle gangs Friday night.

The incident took place around 9:00 p.m., at HWY 62 and 102 in Lincoln County.

According to Lincoln County Sheriff Charlie Dougherty, one victim was shot in the leg following an altercation between two "biker gangs", the Redneck Rough Riders and the Iron Order.

Investigators said at least three people opened fire, and the shooters were from both gangs. 

"A couple of them blocked off a guy and an altercation took place, and from that point it became a gun battle," said Lincoln County Sheriff Charlie Dougherty.

One of the men ran toward the casino for cover but a security guard stopped him. According to the Kickapoo Casino's Twitter page, they were under a lock down but it was lifted around 10:30 p.m.

The shooting victim suffered non-life threatening injuries. 

At this time, authorities have detained at least three suspects involved. No word yet on why the altercation started.
