Recent comments by category

I’m trying to get a list of recent comments (the latest) from a specific category, but I don’t get it to work.

When I use the “normal” code it gives me comments from all categories:

<?php
$args = array(
	'status' => 'approve',
	'number' => '5',
);
$comments = get_comments($args);
foreach($comments as $comment) :
	echo($comment->comment_author . '<br />' . $comment->comment_content);
endforeach;
?>

I also found this code, but it just gives me 1 comment, and I want the 5 latest:

<?php
$show_comments = 20;
$i = 0;
$comments = get_comments("status=approve");
foreach ($comments as $comment)
{
	$comm_post_id = $comment->comment_post_ID;
	if (!in_category("nyheter", $comm_post_id))
		continue;
	$i++;
	?><li><?php comment_excerpt(); ?></li><?php

	if ($i >= $real_comments) break;
}
?>

Any help?
