Getting Recent Post in a category Coding Help

Hi guys,

I was trying to pull out the entries under a certain category but my code is not working.

<?php $recent_posts = wp_get_recent_posts();
       if (in_category('6')) {
	foreach( $recent_posts as $recent ){
		echo '<li><a href="' . get_permalink($recent["ID"]) . '" title="Look '.esc_attr($recent["post_title"]).'" ><img src="' .   get_post_meta($recent["ID"], 'Thumbnail', true).'"><span>'.$recent["post_title"].'<br /><br />'. get_post_meta($recent["ID"], 'Short Description', true) .'</span></a></li> ';
	}
     }?>

did I do in_category correctly? or is there some other way how to do it?

Thanks in advance.
