Here are the details, via a story from The Associated Press:
Derek Fisher is seeking a temporary restraining order against a woman who he says is stalking and harassing him. The Lakers guard, who is playing in Game 5 of the NBA playoffs against Utah, filed the paperwork with the Los Angeles County Superior Court earlier Monday.
He claims that the woman, Symone Fisher — no relation — has been harassing him since 2001 but that the situation has gotten worse over the past few months. Fisher claims that the woman has been showing up at his place of work and at his private residence.
In the restraining order, he also asked for protection for his wife, Candace, and four children. A Los Angeles County detective investigating the case recommended that Fisher get a restraining order after looking into a number of unsolicited e-mails, internet messages and letters sent from Symone Fisher suggesting that the two were married.
