Grand Theft Auto IV Tips

Getting Rid Of Your Wanted Level
After escaping the 'catchment' zone (the circle that appears around your last known position - i.e. where the Police saw you last) DO NOT drive on, instead stop right outside of the zone, and wait for the police to stop searching.

If you simply drive on, there is a high chance that you will run into some policemen which will refocus the catchment zone around you. If you wait just outside of this zone, the chance for the police to come there is lower, and after a few seconds (I believe 5 - 10 seconds of waiting) the police will call off their search.
