LEAGUE CITY -

The League City Police Department said patrols have been increased at all schools in that city after a case of stranger danger. And the school district says it's the third such report in the last week.

Parents Local 2 spoke with are worried about what's going on.

"It really scares me and makes me wonder what my kids will do and hopefully they will know to run away," Becky Halligan says.

The first incident happened Thursday at Clear Lake City Elementary School where police say a woman driving a van asked a young girl if she needed a ride.

Then on Friday at Parr Elementary School a little girl was approached by a man driving a white van.

Finally, a child was walking home from school Monday when he was approached by a stranger, according to police. The child said the man asked if he was locked out of his home and asked him to get into his car. The boy ran to a neighbor's home to report the incident.

The stranger was described as a male in his 60s with white hair. Police said he was driving an old four-door vehicle with faded red paint.

No child was ever touched or hurt according to investigators.

After all three incidents, police have increased patrols at all three schools.

In a letter to parents, Clear Creek ISD Superintendent Greg Smith said: "The safety of our children is of the utmost importance to my staff and employees across the Clear Creek Independent School District.  I want you to be assured our focus on safety does not begin and end at the campus door.  I also want you to know that in the last week we've had reports of strangers asking students walking home if they wanted a ride in neighborhoods near Clear Lake City Elementary, Hall Elementary and Parr Elementary. In all three incidents the students did the right thing, moving away from the vehicle and telling an adult what happened."

League City spokeswoman Reagan Pena said, "We are going to heighten the presence in the school zones both before and after school here in our elementary schools in League City. We would encourage parents to take the opportunity now to talk with their kids."

Police say citizens should look for license plate numbers, make and model of the vehicle, direction of travel, and any stickers or defects on the vehicle. They also remind citizens to report any suspicious behavior directly to the police department or by calling 911.
