How to remove chrome app icons from launchpad?

I uninstalled Google chrome by deleting it from the Applications folder and I also deleted the associated profile data from ~/Library/Application Support/Google/Chrome. But I have failed to remove all the Chrome apps icons from launchpad. I would greatly appreciate it if you can point to the location where google is keeping those app launchers. I have looked for them in the hidden folders as well as Google folders in ~/Library but I have had no luck.
