The sexual assault suspect is identified as John Christopher Munoz, 19, of Hollywood.
Police say early Friday afternoon, Munoz scaled a wall, climbed onto a garage roof and forced his way through a balcony window of a home in the 100 block of South Van Ness Avenue.
Detectives say he attempted to rape a 56-year-old woman working in the home. She was able to fight off the attacker and he escaped.
Despite an intensive manhunt, which included a canine search, police were not able to find the suspect.
The next day, Olympic-area patrol officers detained Munoz, based on the physical description of the suspect.
Munoz is being held at Parker Center Jail on $375,000 bail.
Anyone with information is asked to call West Bureau Sexual Assault Detail Detectives A. Mercado or L. Nunez at (213) 473-0447.
