Your CW could definitely file charges, though. The man was chasing her and screaming at her to stop trying to contact the police. She obviously felt threatened because she was running while dialing 911. I think it would be in your CWs best interest to file charges and get a restraining order to keep that asshole away from her workplace and home.
I agree. These jerks know where you work, he might try something with her.
I wish you and your other coworker a speedy and thorough healing.
ETA: Just reread the post, and saw this bit:
Me: Where’s *female co-worker*!!!???
I hear a scream. FCW is being chased down the street by the other guy. I hear him yell “GET OFF YOUR FUCKING PHONE BITCH!”
CW2 and I chase after him. I am in that much of a state that I can’t even run in a straight line. By some miracle we caught up with him before he got to FCW and grabbed him.
“I haven’t hit anyone pal!”
Me: Then why the fuck are you chasing her?!?
“I just wanted to make sure she was OK!”
Yeah, she should definitely file charges and get a restraining order. “GET OFF YOUR FUCKING PHONE BITCH!” is not what you say to someone when you're wanting to check if they're okay, it's what you say when you're intimidating a witness, as Shalom pointed out.
