LONDON (AP) David Nalbandian has been fined the maximum $12,560 and faces a police investigation into an assault complaint after kicking an advertising board and injuring a line judge during the Queen's Club final.

The ATP confirmed the fine for unsportsmanlike conduct on Monday. Nalbandian also was stripped of his $57,350 in prize money.

London police declined to say who made the assault complaint against Nalbandian, who was defaulted from Sunday's match against Marin Cilic in the grass-court Wimbledon warmup 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.
