UPDATE 3:06 PM PST: In the documents, Timberlake claims McNeil is an "obsessed mentally unstable celebrity stalker, who [Timberlake] does not personally know."
According to legal documents, obtained by TMZ, McNeil rolled over to Timberlake's house in a taxi on October 22, bypassed security measures, "trespassed onto [Timberlake's] property, attempted to gain access into his home, and delusionaly claimed to know and be friends with [Timberlake]."
Timberlake's security team eventually apprehended McNeil, who is described as a "heavyset white female, approximately 50 years of age." Justin's people also believe McNeil "appeared to be a transient."
UPDATE: We're told LAPD cops took McNeil to a local hospital for a 5150 psychiatric evaluation. Sources say the individuals who evaluated her felt McNeil did not meet the criteria for a 5150 hold so she was released.
