LONDON : Three women from the United Arab Emirates were in hospital on Monday after being savagely attacked in their room at a luxury London hotel by a man wielding a hammer , police said. 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 are treating the attack as attempted murder, although they said they had an open mind as to the motive.
