Deleting files from your plugin hosted in WordPress repo

I have a plugin hosted in WordPress plugin repo svn and recently I was doing some code refactoring and want to remove an old file.

When I do a commit after the svn delete command, I am getting the following error

$ svn delete util.php
D         util.php
$ svn ci  --username=sudar -m "Delete old files"
Deleting       util.php
svn: E195023: Commit failed (details follow):
svn: E195023: Changing file '/private/tmp/new/trunk/include/util.php' is forbidden by the server
svn: E175013: Access to '/!svn/txr/1104304-ot2y/bulk-delete/trunk/include/util.php' forbidden
svn: E175013: Access to '/!svn/txn/1104304-ot2y' forbidden

Is deleting files from WordPress svn repo prohibited? Is there a way to remove files?
