Yes like:
Step 1:get player's Position whose you want to show on map.

PHP код:

new Float:X, Float:Y, Float:Z;
GetPlayerPos(giveplayerid, X,Y,Z); 


Step 2: Then SetPlayer's Checkpoint on map.

PHP код:

 SetPlayerCheckpoint(X,Y,Z); 


Tip: you can use Timer on OnPlayerUpdate to check Player's position every 2 or 3 seconds to chase him... basically its Good for RPing the Pursuit, so Other players can see Suspect's current location on Map.. Hope that solved your doubt
