Police began searching for Damani Johnson after he left Russell Elementary School around 3:45 p.m. Monday.
Family members were very concerned, because they said Damani is on medication.
According to the LAPD's Southeast Division, Damani walked into the Inglewood police station around 6 p.m. Monday, but authorities were not notified until after midnight due to miscommunication.
Damani apparently ran away because of an argument with a family member, police said.
