Rapper Big Sean's house in Hollywood Hills was broken into while he was away on a trip to Dubai.
Sean's unpublished music and his $150,000 worth jewellery were stolen, reports tmz.com.
After an initial investigation, police believed it was an "inside job". The detectives "think the thieves knew Sean was in Dubai and had a clear layout of the house".
The "Blessings" hitmaker hasn't commented on the burglary, but he posted a series of pictures from his trip instead.
