A 17-year-old who broke out of juvenile hall was taken into custody Friday, but three other teenagers who escaped with him, including one jailed for attempted murder, remained at large, police said. Probation officers learned that Kenny Mack was at a friend’s house and went there to take him into custody, said Officer Mike Lopez. Mack and three other 17-year-olds used bed sheets to climb out of a unit of the Barry J. Nidorf Juvenile Hall in Sylmar before dawn Thursday, police said. They later carjacked a motorist by pretending they had a handgun and forced him to take them to South Los Angeles, where they fled, according to authorities. The driver was not hurt.
