The man, looks 40+, living next door, looks so creepy.

As we share the same corridor, this evening around 7 pm, he slowly walked pass by the corridor twice and stares inside the house.
At the second time when he is passing by, I notice he stares inside. He is not wearing top
and only wearing pants. Then I take photo for evidence and he started shouting at me and my friend. He has been harassing us with false accusations that we've been making noise talking inside.
Then I go and closed the door and he shouted and threaten us outside.
Actually we turn on TV with normal volume and my friend is watching through the kitchen when preparing dinner.
I was at living room and playing phone. We are just chit chatting about the movie but not making such noise as he said.
Should I report this to police ? I am scared as we are 2 ladies tenant and our landlady is seldom home. Pls advise me. Many thanks.
p.s. This is my fist time post in forum.. pls forgive me if it is irrelevant.
Thanks
