Two taggers spray painted a 6-year-old boy's face and body after he spotted them scrawling gang signs on a wall, officials said Wednesday.

Los Angeles County Sheriff's Capt. James Hellmold said the boy suffered burns to his eyes in the June 25 attack and was sprayed over his arms and other parts of his body. He suffered no permanent damage and was doing well, Hellmold said.

"This definitely shocks the consciousness and is out of the ordinary, even in the gang culture," Hellmold said. "It makes no sense to the normal human being."

One of the suspects, a 15-year-old accused of dispensing the spray, was arrested Tuesday and charged with assault with a caustic chemical, kidnapping and felony vandalism. His accomplice, who allegedly restrained the boy, remained at large. Sheriff's deputies estimated him to be between 15 and 17 years old.

The two suspects were tagging a wall in Willowbrook, an area rife with gangs just north of Compton.
