The incidents occurred around Landings Apartments in Westland, 7000 Lakeview Boulevard.
Nicole Loring and her 4 and 2 year olds live at the Landings and said the recent cases at the complex are disturbing.
"I don't like to hear about people coming up to kids around here," she said.
Westland Police say earlier this week a black man with a beard, in his 20s or 30s, wearing a dark skull cap and hooded sweatshirt , approached 15 year old boy in the apartment complex.
"In one incident, the subject said very rude inappropriate things to the juvenile," said Lt. Matthew Price, Westland police. "We're still trying to find leads on that."
Police say the teen walked away from the vehicle and the man drove off in what's believed to be a gray mini van.
Then on Thursday, police responded to another call from the complex when a suspicious gray mini van was spotted circling the area as the caller waited for her child to get off a school bus.
In the second incident the man is described as white but police believe they're only looking for one person.
"Due to age of victim when stuff happens like this it's kind of shocking to individual, so it's most likely the same person," Price said.
Another woman who also lives at the same complex, says she experienced a stranger danger case at the complex in December.
"I was parking but I saw this man coming my way," said a resident who only gave her name as Tasha. "And I did not get out of the car. I honked my horn and then he turned around and went other way."
Police say they are responding to these recent cases of stranger danger by increasing up patrols.
