SEATTLE -- Detectives are looking for witnesses to a diamond heist Tuesday on Interstate 5 where two men reportedly caused a car to stop, broke the car's windows and stole a bag of diamonds worth $400,000, according to a Washington State Patrol news release.

State Patrol first received a call about 3:48 p.m. Tuesday of a reported carjacking on the exit from westbound State Route 520 to northbound I-5.

According to the release, the victim said he was driving in the Seattle and Bellevue area to jewelers, who are clients, and was on his way to a client in Seattle.

When he exited SR 520, a dark colored sedan reportedly made a sudden lane change and slammed on the brakes, causing the victim to brake and come to a stop.

A second vehicle then intentionally struck the victim's car from behind, according to the release.

That was when two men wearing bandanas reportedly approached the victim's car and broke the front windows, hit the victim and grabbed a bag containing $400,000 worth of diamonds, the release states.

The two men also reportedly grabbed the victim's phone, the key fob for the car and a large suitcase.

The victim's phone was later discovered through tracking in a grassy area at 650 Northeast 42nd Street in Seattle.

Detectives are asking for anyone who witnessed the incident or has information to contact detective Vik Mauro at 425-401-7746 or at
