From KTVU in San Francisco:
SAN FRANCISCO - Surveillance video purportedly shows the ghost of a girl haunting a San Francisco nightclub that was once a mortuary.
KTVU recently received this brief surveillance video clip from San Francisco nightclub the Chapel.
What you are seeing is the club's late-night janitor locking the venue's side door at around 5 a.m.
The video jumps to a few minutes later when a girl appears from out of nowhere.
She runs and jiggles the door handle, then runs back out of frame.
The janitor says he was alone that night and when he saw the clip, he had no explanation as to who the girl could be.
The Chapel occupies a historic Mission District building that was originally built as a mortuary in 1914.
