Megan Thee Stallion & Tory Lanez Swarmed by Cops During His Gun Arrest

Multiple cops descended upon Megan Thee Stallion and Tory Lanez during his gun bust, in what proved to be quite the dramatic scene in the Hollywood Hills.

TMZ got video of Tory's arrest from early Sunday morning, and it's pretty clear ... law enforcement was treating the situation very seriously, as if there might've been an active threat. Remember, they were responding to a call about 5 shots fired with the description of the SUV that was Tory's ride.

What's interesting here from the footage is that they detained everyone in the vehicle. You see a woman being told to exit the vehicle from an officer using a bullhorn off-camera -- while a helicopter is hovering above the whole time -- and you even hear her say, "My hands are up" as they direct her to walk back and get on the ground.

As that's happening, you can see another woman on the sidewalk who appears to be injured. It's unclear which one is MTS. Later, you see the same woman seated on a ledge, and at one point you can hear her turn her head and ask, "Megan are you OK?" ... making it seem like the injured woman is MTS. Tory was also nearby when the woman asked if Megan's OK. Remember, they'd all been hopping between pool parties on Saturday evening.
