Three women from the United Arab Emirates are in a British hospital after being savagely attacked in their room at a luxury London hotel by a man wielding a hammer, police say.
The women, all in their 30s, sustained serious injuries to their heads and faces during the "unusually violent attack" at the four-star Cumberland Hotel in the early hours of Sunday morning.
Three children were sleeping in an adjoining room at the time but they were unharmed.
One of the victims is in a critical but stable condition at a central London hospital, while the injuries suffered by the other two women are not life-threatening, police said.
Detectives were treating the attack as attempted murder.
Officers were called at 1.50am (1050 AEST) on Sunday to the hotel near Hyde Park following reports of an assault, the Metropolitan Police said in a statement.
"At this stage, it is believed that a single male suspect entered a guest bedroom on the seventh floor of the building, where three women and three children were sleeping in adjoining rooms," it said.
"Detectives believe that the suspect was disturbed when some of the occupants of the room woke up, and the three women were subsequently assaulted with a hammer which was later recovered at the scene."
