Authorities in Orlando are investigating a report that $400,000 worth of diamonds were stolen from a man's car after he left them in a bag on the front seat while he ate at a buffet restaurant.

The 47-year-old man from New Jersey called officers and said his car had been broken into and a bag had been stolen while he was eating dinner Monday night.

"The victim stated that the bag contained about $400,000 worth of diamonds," Orlando Police Sergeant Jim Young told MyFoxOrlando.com.

Young says authorities aren't sure whether this was a planned diamond heist or if the thief just got lucky.

"Vehicle burglars look for opportunity. In this case, there was opportunity of a bag sitting on the seat, so obviously the criminal took that opportunity and took that bag," he said.

It is unclear why the man had so many diamonds in his possession.
