Assault complaint against Nalbandian probed

London police declined to say who made the complaint against Nalbandian, who was defaulted from Sunday’s match against Marin Cilic in the grasscourt Wimbledon warm-up event. Any member of the public who witnessed the event in person or on television could have made a complaint, as could the line judge himself. Nalbandian won the first set 7-6 (3) but lost his temper after losing serve to fall behind 3-4 in the second.
