K.C. Amos, son of "Good Times" star John Amos, was arrested after allegedly threatening his sister with guns as the family continues to feud over their father's health. 

According to TMZ, "John's son, K.C., was busted last weekend after his sister, Shannon, claimed he sent her a slew of concerning texts, which she says made her fear for her life." Shannon also told police about her brother's purported gang affiliations and sent videos of him firing a handgun along with the message, "Gonna sleep much better tonight big sis."

TMZ also notes that "a spokesperson for the Essex County Prosecutor's Office ... Shannon said K.C. suffers from bipolar disorder, which has led him to believe she hired someone to kill him."
