I would also check a couple other areas. It sounds like this is almost a type of notification, so you may want to view his application settings and see if anything that appears a little sketchy is there. You can probably then remove it or disable it from sharing notifications.
In addition, this might sound like a silly one, but are you sure that the link isn't embedded into his wallpaper? If you can't interact with the link from the lock screen, then try changing the wallpaper to one of the Apple included ones via the settings menu. If the link still hangs around, that's probably not an issue.
Two final thought from me, is this device jailbroken? This would make it much more likely that it is truly a piece of malware messing with the system. And, if all else fails, wipe the thing and set it up as a new iPad without restoring from backup (once you safely get his hard to replace data off of the device through a system other than iTunes backups). Just like a PC, sometimes the most effective solution is just to start from scratch.
