Over the weekend, a routine traffic stop became a significant bust for the Union City Police Department. Last Saturday, Officer Moya decided to pull over a motorist for violating a vehicle code, specifically an expired registration for over a year. The stop led to the discovery of suspected drugs and an illegally possessed firearm and the subsequent arrest of the driver, who was found to be a convicted felon. This information was disclosed in a recent social media post by the Union City Police Department.
