Moraga police Friday said they had not heard from the young girl a passerby reportedly saw being assaulted on a walkway between Camino Pablo and Kazar Court in Moraga.
Lt. Jeff Price said no one has contacted the department with additional information on the sighting, and no one reported being the victim of the assault.
"We were obviously concerned, based on what was reported to us," Price said.
Moraga police, supported by Lafayette police units, scoured the area shortly after a boy walking in the area reported an older man assaulting a young girl at 10:30 a.m. Thursday.
Neither the man, described as being in his 20s, or the girl, were located.
