Tuolumne County sheriff's officials were looking for a man who offered a ride to a group of children waiting for a school bus Tuesday morning in the Columbia area.
The incident occurred about 7:30 a.m. as the Columbia Elementary School students were walking to the bus stop at Parrotts Ferry Road and Columbia Village Drive.
The man, driving a newer model navy-blue Jeep, approached the children from behind, said sheriff's spokesman Sgt. Jeff Wilson.
The vehicle appeared similar to a Jeep Grand Cherokee.
Wilson said the man asked the children if they had missed the bus before offering them a ride. The children ran away.
Wilson said a woman who witnessed the incident tried to approach the man, but he drove away slowly, watching the children in a suspicious manner.
Sheriff's officials described the man as being in his 50s or 60s with short gray hair, green or blue eyes, full teeth, no facial hair and thin eyebrows. He was wearing reading glasses and a zip-up khaki windbreaker.
Investigators ask anyone with information about this man or the vehicle to call the Sheriff's Department at 533-5815.
