Officers tried pulling a truck over near the intersection of Blackstone and Belmont around 5 pm Tuesday.
The truck didn't stop and led police on a short chase that entered southeast Fresno.
Officers say the suspect was approaching the Fresno Fairgrounds and they wanted to stop him before he reached the area.
That's when they used a pit maneuver to crash into and bring the runaway truck to a stop.
Police found a gun inside the suspect's vehicle.
The man driving the truck and his passenger have both been taken into custody.
