NORWALK - Norwalk school officials are warning parents following new incidents of stranger danger.

The latest incident happened Tuesday near Nathan Hale Middle School. One student told police that someone in a dark van drove near her on Walker Avenue.

Another student reported a similar incident on Monday. She says that two weeks ago, a man in a dark van asked her to come over and talk with him.

The Norwalk superintendent of schools has sent a note home to parents warning about these incidents.

News 12 Connecticut reported about similar incidents in Norwalk earlier this month. Police don't think they're connected.
