JACKSONVILLE, Fla. -

Since school started in Jacksonville last week, there have been at least four police reports filed of men trying to entice girls into getting in their cars.

The news is alarming for many concerned about recent kidnappings and assaults.

The alleged incidents happened on four different Southside streets: San Jose Manor Drive East, Barnes Road, Carranza Drive and Beach Boulevard.

Investigators say that a teenage girl was walking to school last week on a sidewalk near Beach and San Pablo Road when she was approached by a man in a red Pontiac.

He tried to get her in the car, but she said no and kept walking, according to a police report.

Investigators say the man then followed the girl a few blocks away, got out of his car and tried to grab her, but she was able to run away.

"I saw a little girl walking along the street minding her own business, and this gentleman was driving right along side of her," said a witness who didn't want to be identified. "When he was trying to get her to get into the car, we asked her if she wanted to come get inside."

The woman said she was headed to work before 6 a.m. Aug. 21 and saw the man following the 16-year-old girl.

"'Hey girl, why don't you get in the car? What's your name? Why don't you come with me?'" the woman said the man asked the girl. "She was just like, 'He kept asking me questions. He wouldn't leave me alone.' He was very insistent on her getting inside the car."

The woman and her mother offered to help the girl, but she kept going. Then, according to the police report, the man kept trying until the girl screamed and ran toward Beach Boulevard.

"It's very alarming, very alarming," the woman said.

There have been at least three other similar incidents reported to the Jacksonville Sheriff's Office in the last week and a half. In each case, girls between the ages of 12 and 18 accuse a man of trying to get them into his car.

One time a man said, "Come here because I have something for you." Another time, a girl reported a man asked her, "Do you want some candy?" and "Are you sure you don't want a ride to school?"

Detectives are still working all the cases, but police said they don't see any connection.

"There is no pattern or trend. Not one report has a similar area, similar suspect description, or similar vehicle description," JSO spokeswoman Melissa Bujeda said.

Channel 4 crime and safety expert Ken Jefferson says the incidents should have parents and children on high alert, and whether or not the men had bad intentions, it's important to report anything that may seem out of the ordinary.

"That's what we will have to do, because we don't want to have another incident like we've seen in our city where we have another child as a victim," Jefferson said.

There was surveillance video of what happened last week here at Beach and San Pablo that it shows a red Pontiac Grand Am, but the man inside nor his license plate are visible.
