public AreaTimer()

    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(IsPlayerConnected(i))
      {
            if(IsPlayerInRangeOfPoint(i, RANGE,X,Y,Z) && IsPlayerARobber(i)) // change to whatever you have
            {
                SetPlayerWantedLevel(playerid, 4);
            }
            else
            {
        SetPlayerWantedLevel(playerid, 0);
            }
