pawn Code:

COMMAND:arrest(playerid, params[])
{
    stunedid = strval(params);
    if(gTeam[playerid] == TEAM_ENFORCERS)
    {
        if (strval(params)>0)
        {
          if (Stuned[stunedid] == 1)
          {
            new rand = random(sizeof(JAIL));
            SetPlayerScore(stunedid,GetPlayerScore(stunedid)-10);
            GivePlayerMoney(stunedid,-1000);
            SetPlayerPos(stunedid, JAIL[rand][0],JAIL[rand][1],JAIL[rand][2]);
            SetCameraBehindPlayer(stunedid);
            SendClientMessage(stunedid,COLOR_GREY,"* You have been arrested! You lost 10000$ and 10 Score");
            GameTextForPlayer(stunedid,"~r~ARRESTED!",3000,3);
            SetPlayerScore(playerid,GetPlayerScore(playerid)+10);
