Lawrence police received a second report Sunday about a man exposing himself to children in the Sunset Hill neighborhood, which officers have connected to a similar report on Thursday.

A 13-year-old girl told police she saw a car twice as she was walking home from a friend’s house about 5:30 p.m. Sunday, a police report said.

First, in the 900 block of Wellington Road, she said she saw the door open and a leg extend from the vehicle, police said.

Then, as she approached the cul-de-sac in the 3200 block of West Ninth Street, police said, “she reported that she saw the driver open the driver’s side door, place both of his legs outside the vehicle, expose himself to her and then begin making motions with his hand.”

The girl ran home and notified her mother, who called authorities.

On Thursday, a man reportedly exposed himself to a 12-year-old girl in a parking lot near the playground at Sunset Hill School, 901 Schwarz Road. The incident occurred just after 7 p.m., as the child and a 10-year-old girl were playing near the school.

The 12-year-old told police that a man in a white car opened the door and had his pants down. Both girls reported the incident to their parents, who called police.

In both cases, the suspect was in a small, newer model white four-door passenger car, police said. The man’s vehicle was recorded on surveillance video at the school.

Police said officers have increased their patrols in the area, in response to the incidents.

“It is a serious situation,” said Sgt. Bill Cory, police spokesman. “Things can escalate and we want to prevent that from happening.”

Sunset Hill School officials notified parents about both incidents using an electronic messaging system.

“There is a nervousness, but we need to all be vigilant in keeping our eyes out and having a safe neighborhood,” said Chris Bay, school principal.

In the Thursday incident, the suspect was described as a white man, about 20 years old with black hair and long sideburns.

Anyone with information is asked to call the Crime Stoppers hot line at 843-TIPS.
