Authorities in Central Iowa are investigating two reported incidents of strangers allegedly trying to pick up students outside schools. According to KCCI-TV in Des Moines, Des Moines Public School District parents received an email from school officials, claiming a man tried to convince a middle school student to get into his vehicle near Moulton Elementary School.

The school district said the vehicle was a black Range Rover with tinted windows and described the man as being heavyset with dark skin and a nearly-shaved head. The man appeared to be in his early 30s and had facial hair, according to the school district.

Parents of students in the Prairie City-Monroe Community School District said they received an e-mail about an incident that allegedly happened Wednesday afternoon, outside the Monroe Elementary School. During the incident, a woman and two men in a silver car approached a female student and claimed the girls’ parent asked them to pick her up and take her home from school.

The driver of the car was a woman with red, bushy hair. The men were wearing T-shirts with cut-off sleeves.
