The breach seems to happened around 01:03:25. It's hard to tell but it looks like a door was either breached or opened to the far left. There is a loud thud happening at the same time but it's hard to tell if that's what caused it. It's seems to be off the side of the barricades so it doesn't appear anyone was "let in".
