There's plenty of opportunities to gain this achievement. In many cases or street crimes a suspect will make a run for it.

After a while the suspect will slow down and as you get closer you'll be prompted to tap . When this happens, tap rapidly to get a sudden burst of speed and you'll then make a dive and tackle the suspect.

While chasing a fleeing suspect you will have the optional to tackle the suspect, but only if Cole doesn’t have his gun out. If Cole's gun isn’t out you will need to stay close to the suspect. Once you are close enough, you will be prompted to press rapidly; you will see Cole start to run a lot faster, there will be a short cutscene once you get close to the suspect to tackle him.
