KANSAS CITY, Kan. --Two police officers from different departments report being followed just before hearing popping sounds, and investigators believe it may be the same suspect in each case.

Police have not released a description of the suspect vehicle, but they believe it was the same vehicle in both cases.

The first incident happened on Wednesday night around 9 p.m. A Lenexa, Kan., police officer riding a motorcycle was headed eastbound along I-70 when a vehicle was following him very closely. Each time the officer changed lanes and sped up, the driver did the same. When the officer got off at I-70 and 670, he heard a pop and saw the passenger standing up out of the sunroof.

Lenexa police say they cannot confirm whether the popping sounds the officer heard was actually shots fired.

Then on Friday, July 22 around 8 p.m., in the same area, another police officer, this time from Kansas City, Kan., experienced a similar situation. The officer changed lanes, so did the driver. The officer could not get rid of the car following him. As the motorcycle officer got off the highway, witnesses describe a passenger standing up outside the sunroof and hearing a popping sound.

Neither officer was hurt.

This is an ongoing investigation.
