LOS ANGELES (AP) _ Gang members hit the mayor's mansion with graffiti a few days after Mayor Richard Riordan began trying to shut down houses believed to be gang hangouts.

It was not known if the graffiti found Friday came in retaliation for Riordan asking the city attorney for an injunction to close alleged gathering spots for members of the 18th Street gang, but the graffiti came from the gang.

``The graffiti was generic in nature for the 18th Street gang,'' police Lt. James Miller said.

The Getty House, located in Hancock Park, was defaced with a marking pen on a post and a gate. The graffiti was removed shortly after it was found.

Riordan does not actually live at Getty House, an English Tudor mansion used for receptions and other official functions. He lives at his home in Brentwood.
