LITTLE ROCK, Ark. (KTHV) - The Hillcrest Historic District is said to be one of Little Rock's oldest neighborhoods and according to police, one of the safest. But for the last week, officers have been looking for a man on the loose.

"We've got officers in place pretty much 24 hours a day. We have no doubt we'll catch this guy. It's just a matter of time," says Lt. Terry Hastings with Little Rock Police.

Hillcrest residents are reporting a man exposing and touching himself inappropriately in front of children.

"He supposedly followed one of the children but when she called on the cell phone, he turned and ran away," says Lt. Hastings.

Little Rock Police say the suspect has been spotted in various parts of the Hillcrest area. From the 3400 block of Lee Avenue to the Fletcher Library, each time he is hiding his identity.

"It's a white male in a ski mask in a dark colored jeep," says Lt. Hastings.

Although he has not attempted to physically harm any of his victims, Lt. Hastings says it isn't out of the question.

"It's a very dangerous situation. It is one of those things that you don't know what the real intention of the suspect is so that's why we have to assume the worst, that he is trying to kidnap a child," says Lt. Hastings. "We encourage folks to talk to their children about this. If you see suspicious activity, call police immediately."

Little Rock Police is working with neighborhood watch programs to make as many residents aware as possible.

There are ways you can talk to your children about these kinds of dangers. Safety Cops is a website developed by police agencies that can guide you through the conversation.
