A Chatsworth man who police say carjacked a vehicle and then attacked three women in a Sherman Oaks nail salon was in custody Thursday. Gustavo Aranda, 25, was arrested about 10 a.m. Wednesday at the salon in the 13600 block of Burbank Boulevard, according to the Los Angeles Police Department. Police say the carjacking happened just before 8:30 a.m. Wednesday on the 14400 block of Gilmore Street. Nearly an hour and a half later, Aranda entered the nail salon, where police said he began “hitting three women inside for no reason.” Video of the incident appears to show Aranda swinging a chair and attacking the victims until employees from a neighboring business arrived and restrained him. Two of the women, sisters, immediately fought back, hitting Aranda with chairs as he attacked them, video from a security camera shows.
