A second suspect is now in custody in connection with a mass shooting that injured nearly a dozen people earlier this month in Kansas, Wichita police announced Monday.

A 27-year-old man was arrested on suspicion of aggravated battery and possession of a firearm by a felon. On Friday, a 19-year-old man was arrested. It wasn't immediately clear if either man has been charged. Their names have not been released. A message left with Sedgwick County District Attorney Marc Bennett wasn't immediately returned.

In addition to the arrests, police are searching for a 23-year-old man believed to have been involved in the shooting. A St. Louis-area man was arrested July 3, but prosecutors later determined he fired his gun to defend himself after shots were fired by two other men at the club.
