GTA 5 Online secret locations — GTA 5 Online: Map of all underground secret locations and interiors revealed

Renowned YouTuber, MrBossFTW, has showcased the map details of nine secret underground locations and interiors in his latest gameplay video for GTA 5 Online, with due credit to an employee working at Grand Theft Auto Network France (GTANF) with the Twitter handler Yan2295.

Yan2295 takes credit for creating the map depicting the nine hidden underground locations and later leaking this information over Twitter as well as on GTA forums website.

As MrBossFTW notes in his video, you will need to know how the original wall-breach works in GTA 5, in order to access all these secret locations.

Here is how you do it:

Just get right behind the Police Station in Vinewood and walk right up to the wall under the bridge (as shown in the video below) and then climb over a vehicle or some object near the wall, before you make the jump that will enable you to perform the wall-breach.
Just hop over the ledge as shown in the video and then climb over the wall to activate the glitch, which gives you secret access to the bridge.
Now, just jump down to experience the free-fall as the glitch kicks off all over the map and makes you ethereal with special abilities like walking through the wall or falling through the floors.
Tip #1: You must note that you will need a parachute to successfully execute this glitch without getting killed, as you will enter a free-fall, once the glitch kicks in.
Just open the parachute once you start descending, and you will now be able to float around the various secret locations in GTA 5.
Tip #2: You will only get 20 to 30 seconds to get to any of these secret locations, before you hit the rock bottom or you are teleported right back to where you started the glitch on the map.

Check out all the secret locations that are earmarked on the map with yellow boxes and numbered from 1 to 10, in the screenshot below:
