UPDATE 2: WXYZ is now reporting that GM has not fired the valet, 32-year-old Didarul Sarder, for brandishing his firearm to stop the alleged assault. Again, we're following this story as it develops. An employee at the General Motors Tech Center in Warren, MI, was stabbed multiple times with a steak knife today after she was approached by another woman in the lobby of one of the sprawling facility's buildings. The employee is currently listed in critical condition at a local hospital and is undergoing surgery for wounds to her neck, abdomen, and back, Warren Mayor Jim Fouts told The Detroit News. The incident occurred around 9:00 a.m. when a female visitor entered the facility and asked for an employee by name. The pair were speaking and then stepped outside, where the alleged assault took place. It was stopped by a valet driver with a concealed pistol license who brandished his weapon, Fouts said. Neither the victim nor her alleged assailant are being identified at this time. "Had I been looking, I could have viewed this attack taking place. You just don't expect something like this to take place," Fouts, whose office sits directly across Van Dyke Avenue from the Tech Center, told The News. "It's unprecedented, unexpected, and unbelievable." General Motors confirmed to The Detroit Free Press that the alleged attacker is in custody and that the company is cooperating with Warren Police. A full statement on the incident is expected later today.
