A woman was found dead under mysterious circumstances inside the bathroom of a luxury hotel in east Delhi's Mayur Vihar, the police said on Friday.
Police said they were awaiting the postmortem report to ascertain the cause of death.
The woman had checked into the hotel on June 6 with her male friend and her body was found on Thursday.
The woman was working in a beauty parlour in south Delhi and living with her relatives in the city.
Her male friend told police that he had left the hotel on Wednesday to meet his father. He claimed that he made several phone calls on Thursday but they went unanswered. He then informed the hotel staff to check on her but the room was found locked from inside.
The hotel staff found her lying on the bathroom floor with head injuries, they said. Police are probing the matter.
