Hayden Christensen's producer brother was targeted in an attempted robbery this week (begs01Oct12) when a burglar broke into his Los Angeles house.

Tove Christensen, who produced his actor sibling's 2003 drama Shattered Glass, was at home in the early hours of Tuesday (02Oct12) when an unidentified male used a rock to smash a window and gain entrance to the property.

The 39 year old, who was not seen by the intruder, promptly called police to report the crime as he lay low, reports Tmz.com.

The man attempted to steal a guitar but he ran off and dumped the instrument in the bushes after hearing police sirens, and he managed to escape before cops arrived at the scene.

Authorities have since launched an investigation into the incident, although they have yet to name any suspects.
