Answer 2

Reporting incident since you asked:
The tenant told me that they attacked her when she was entering our house in the evening. There was great confusion on the road with traffic jam, and none heard her scream, her face bitten by her attacker. "I'll find out," I replied to her. She left, but her partner was left alone in the PG accommodation.
Two men entered her room at night. I heard her cry, and knocked at the door. She had bloody weals on her face. Who hit you? She did not reply. He was hiding in her room, but I was not sure where."I'll meet you next morning," I told her.
