Officers of the Maloney CID arrested three people in D’Aabadie last night, among them a 17-year-old boy.
The officers were on patrol at around 8.05 pm when they saw a white Nissan B15 speed onto Maggie Hurst Lane and then later collide with another car at the end of street.
As the officers followed the vehicle, they then saw one of the passengers throw a gun out of the car.
A Glock 17 pistol with 11 rounds of ammunition was discovered shortly after and the car stopped.
The three occupants, ages 17, 32 and 50, all from D’Abadie, were arrested.
