Document the times, what happened, entirely without any emotion. Just facts. Make a judgement call whether you trust that managers boss to handle the situation or not. If not then HR would be the correct answer. Just know that nobody will be happy. Not the manager, not their boss or those above them and likely not the victim if they did not want any drama or fallout from the event. HR protect companies, not people so be ready for management to handle this poorly if you decide to intervene. Have you asked your friend what they would like to see happen? They may say they do not remember because they do not want you to do anything unless they were drinking very heavily and truly do not remember. Did anyone else witness this and are they willing to take action? There is power in numbers.

I should add for clarification that even if they spoke to the persons manager, they would be obligated to go to HR regardless. Both routes lead to HR. Also I am not a lawyer. Review the laws in your state or let HR sort it out. Bring witnesses.

She was unable to walk so certainly not in her senses. But that also I doubt how can she get so drunk that she can’t walk , did he give something to her

[LinuxBender]

so drunk that she can’t walk

So hammered. Maybe she legit does not recall and that is where witnesses other than yourself are important.

did he give something to her

Tox screening at the time might have been able to tell but as time passes so do chemicals. If it was Rohypnol she would not have been able to respond to you. Rohypnol will stay in the system for 72 hours. Be very sensitive if she is your friend and you plan to talk to her about this. Hopefully someone trust-worthy gave her a ride home.

She talked to me next day so I guess she was ok, how should I talk to her ?

[LinuxBender]

Express concern. Avoid challenging what she says, just listen and pay attention. If she wishes to not talk about it then move on. Let her know you are willing to be there to help if she wants help. Encourage her to get a toxicology screening if you suspect her drink was spiked. Ensure she is entirely in control. Let her decide the right path.

She was on a vacation just after the party , she said she felt safe because she doesn’t remember anything that happened ,

Should I tell her your manager was hitting on you ?

[LinuxBender]

and then started trying to hit on her and even touch her

Should I tell her your manager was hitting on you ?

Hitting on someone is heavy flirting. Flirting does not involve touching, especially if that person is your subordinate. Either way that is a power conflict. Just tell her what you told us, just the facts. If she wants your help then find out if anyone else witnessed what happened.

To clarify this is if she is your friend. If just a colleague then just talk to HR and let them sort it out.
