The Los Angeles Police Department told Us Weekly the incident occurred outside of the couple's Bel Air home on Friday and the burglar didn't enter the property.
"A witness observed a suspect enter and exit the victim's vehicle and then flee the location," police said. "A second suspect who was hiding in some bushes also fled the location. Suspect No. 1 took personal items from the victim's vehicle."
The suspect broke into three vehicles at the end of West and Kardashian's driveway and was spotted on surveillance cameras, according to TMZ.
After leaving the property the suspect reportedly also broke into a car in the driveway of the couple's neighbor Kathy Griffin.
