How to remove movieclip from array?AS3

Hi here is my code:
var arrows:Array = new Array();
var gameTimer:Timer = new Timer(1000); // 1 second
var maxTime:int;
var Time:int = 2;
var arrow_speed:int = 5;
maxTime = Time;
gameTimer.start();
import flash.display.MovieClip;

function Arrows(event:Event) {

MoveArrows();
if(maxTime == 0){
	if(arrows.length<3){
	
		var arrow_type:int = Math.random()*3;
		trace("Jepu: "+arrow_type);
		
		getArrows(arrow_type);
		maxTime = Time;
		
	}
	
}

}

function getArrows(type){

switch(type){
	case 0:
		var arrow1:Arrow = new Arrow();
		arrow1.gotoAndStop(1);
		arrow1.x = 20;
		arrow1.y = 0;
		stage.addChild(arrow1);
		trace("Object: "+arrow1.name);
		arrows.push(arrow1);
		break;
	case 1:
		var arrow2:Arrow = new Arrow();
		arrow2.gotoAndStop(2);
		arrow2.x = 120;
		arrow2.y = 0;
		stage.addChild(arrow2);
		trace("Object: "+arrow2.name);
		arrows.push(arrow2);
		break;
	case 2:
		var arrow3:Arrow = new Arrow();
		arrow3.gotoAndStop(3);
		arrow3.x = 220;
		arrow3.y = 0;
		stage.addChild(arrow3);
		trace("Object: "+arrow3.name);
		arrows.push(arrow3);
		break;
	case 3:
		var arrow4:Arrow = new Arrow();
		arrow4.gotoAndStop(4);
		arrow4.x = 320;
		arrow4.y = 0;
		stage.addChild(arrow4);
		trace("Object: "+arrow4.name);
		arrows.push(arrow4);
		break;
	default:
}

}

function MoveArrows(){
for (var i:int = 0; i<arrows.length; i++){
arrows*.y+=arrow_speed;
var arrow_name = arrows*.name;
if (arrows*.hitTestObject(del)){
//removeChild(arrows*);
MovieClip(MovieClip(arrows*).parent).removeChild(arrows*);
//trace(arrow_name);
arrows.splice(i, 1);
}
}

}

function runMany(event:TimerEvent):void {
getTimer()/1000;
maxTime–;
}
function main(){

addEventListener(Event.ENTER_FRAME, Arrows);
//addEventListener(Event.ENTER_FRAME, MoveArrows);
gameTimer.addEventListener(TimerEvent.TIMER, runMany);
//Arrows();

}
main();

Now my problem is with this function:

function MoveArrows(){
for (var i:int = 0; i<arrows.length; i++){
arrows*.y+=arrow_speed;
var arrow_name = arrows*.name;
if (arrows*.hitTestObject(del)){
//removeChild(arrows*);
MovieClip(MovieClip(arrows*).parent).removeChild(arrows*);
//trace(arrow_name);
arrows.splice(i, 1);
}
}

}

if I use removeChild(arrows*); to get rid off the mc I get this error:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
and if I use MovieClip(MovieClip(arrows*).parent).removeChild(arrows*); I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Stage@2f1ef99 to flash.display.MovieClip.

So where I’m doing it wrong?

Thanks for advance. =)
