Law enforcement sources tell us Pete and Chase Sui-Wonders were involved in a car accident Saturday night around 11 PM. Our sources say he was behind the wheel of a Mercedes and driving at a high rate of speed through the Flats neighborhood of Bev Hills. Based on photos of the crash site, obtained by TMZ, it doesn't appear Pete went into the property ... but our sources say he did strike it and caused damage. We're told the preliminary view is that drugs and alcohol were not involved here, but an investigation is currently underway. Our sources also say no arrests were made on the spot, and that Pete and Chase were not cited either ... at least not for now, anyway.
