Player says she was filmed in shower at Atletico's grounds (The Associated Press)

Atletico Madrid says it is helping police investigate a complaint made by a player from a second-division women's team who said someone tried to film her in the shower at the club's grounds on Sunday. The unidentified player for Torrelodones went to police after noticing that someone tried to sneak a cell phone through a window while she took a shower after playing against Atletico at the team's Ciudad Deportiva complex just outside Madrid. Atletico Madrid said Tuesday it is doing everything possible to cooperate with authorities investigating what would be a ''very serious'' occurrence.
