Security Guard At The Mall I Work At Keeps Harassing Myself And My Coworkers. Need Advice

Before I ask for specific advice, here are the most important examples of what he has done to us.

1. While I (M18) was on break and in another store (August 5th, 4:23PM) he came up behind me and forcefully shoved his flashlight against my butt (Simulating something going up there). It was unprompted and I had no idea that he was going to do that, since he came up from behind.

2. He constantly comes into the store I work at, and just stares at my female co-worker (F23), once even doing it for about an hour. She gets really uncomfortable when he's in the store, and I feel really bad for her.

3. When we had a trans (mTf) co-worker employed, he would constantly make transphobic remarks towards her (ex. If you went to prison, you'd be put into a men's prison) and routinely call her an "ogre"

4. Not harassment against us, but multiple times he has told us blank face that he is racist. Another time he told us that he lets shoplifters, and drug users go free because he doesn't want to fill the paperwork out to trespass them.

We are located in Minnesota and I plan on going to both the mall and the security company with complaints about him. I just want to know what bills/laws (I don't know legal stuff too well) or crimes he committed, because the mall is notorious for not fixing things unless legal action is threatened.

Please someone help us, these things have been happening for months, and we don't know what to do anymore.
