A male driver asked a female jogger for directions twice in three days last week, following her home in one case and asking her to get inside his van in another, Ann Arbor police said.

Investigators are working to identify the man, who may be linked to two other similar incidents recently, police spokeswoman Lt. Renee Bush said.

Police say the first of the four incidents occurred Oct. 6. A 19-year-old woman was walking south on a sidewalk along Earhart Road near Geddes Road when a white minivan stopped in front of her at 5:50 p.m., blocking her walking path, police said.

The driver offered the woman a ride, but she declined and continued walking, police said. According to Bush, the man again offered the woman a ride. When the woman spotted a friend and waved, the van sped off, police said.

Eight days later, a 39-year-old woman was jogging near the intersection of Earhart Road and Glazier Way when a small, bright yellow car pulled up at 11:50 a.m., and a male driver asked for directions, police said. According to Bush, the car followed the woman home.

Thirty minutes later, another woman was jogging near the same intersection when a car matching the same description pulled up, and a man asked for directions, Bush said. The jogger maintained her distance and provided directions, police said. According to Bush, the woman attempted to get license plate information, but the man backed the car out of the area.

On Oct. 16, the 39-year-old woman who was approached two days earlier was jogging on Lakeshore Drive when a silver Ford minivan pulled up at 7:30 a.m., and the same male driver asked for directions, police said.

After the woman provided directions, the man asked her to get inside the van and lead him to his destination, police said. The woman couldn't see the license plate number because there was plastic covering the plate, Bush said.

The man was described as white, 35 to 40 years of age, clean-shaven, with a medium build and brown, curly hair.
