Police said the stabbing appeared to have happened inside a car in Spring Lake Township, but they were still trying to determine exactly what happened as of 11 p.m. Friday.
Emergency crews responded to a home in the 18100 block of 144th Avenue at about 9:30 p.m. on a call of a man possibly having been stabbed in the neck.
First responders staged momentarily until police made sure the scene was safe to enter.
An Ottawa County Sheriff's sergeant said the man was taken to a Muskegon hospital and his condition was unknown at the time.
He said a deputy was on the way to the hospital to see the victim.
In the meantime a canine unit responded to track the woman, who had gotten out of the car a short distance north of where the victim was located.
Deputy Jeff Somers and his dog, Ranger, followed tracks north to the 18400 block of 144th Avenue, where he said the tracks stopped abruptly and the suspect likely got into a car.
At one point, Fruitport Township Police became involved when they were asked to check out the parking lot around Pin Crest Lanes in the Village of Fruitport.
Officers had not found anything as of 10:15 p.m.
A short time later, police gathered at an apartment in the 14300 block of Apple Drive, where the suspect was being interviewed, but was not in custody as of 11 p.m.
Police said the incident was not a domestic dispute, but would reveal no more information at the time.
