Eight people were tied up on the ground and two of them sexually assaulted during a takeover-style robbery at Bob’s Burgers & Teriyaki in the city of SeaTac on Saturday night, according to the King County Sheriff’s Office.

At least one of the two robbers had a gun when they entered the eatery in the 20000 block of International Boulevard around 9 p.m., said sheriff’s office spokesman Sgt. Ryan Abbott.

The robbers tied up one employee and seven customers, sexually assaulted two women, and stole money, car keys, jewelry and other items from the bound victims, Abbott said Monday morning.

Two suspects, wearing masks, took off in a brown 2006 Ford F-150 that was stolen from one of the customers, Abbott said. The truck has chrome rims, large tires and a lift kit, and its license plate number is C78292P.

As of Monday evening, the suspects had not been found.
