Los Angeles police have one suspect in custody after a security guard at a Westwood home opened fire when four intruders tried to break in early Wednesday morning.

Three other burglary suspects managed to get away.

It happened around 5 a.m. on Lindbrook Drive near Holmby Avenue and UCLA. Police say the homeowner was inside his house with his family when four suspects entered the residence in a burglary attempt.

Police say as one of the suspects tried to drive away, a security guard fired a round at the suspect. 

It is not known if any of the suspects were shot, nor if anything was stolen from the home.
