The Beautiful Day hitmakers caused widespread controversy last year (14) when they collaborated with the multinational company to get the record automatically installed into iTunes users' music library.

Now Alexander Starovoitov, a member of the right-wing Liberal Democratic Party of Russia (LDPR), has asked the country's attorney general to investigate Apple over claims a cover photograph of drummer Larry Mullen, Jr. shirtless while hugging his 18-year-old son Elvis breaks Russian laws on promoting homosexuality.

Starovoitov has reportedly claimed the album art promotes sex between men, and is said to be suing Apple for moral damages on behalf of his son.

In 2013, a nationwide law was passed in Russia banning distribution of material promoting lesbian, gay, bisexual, and transgender (LGBT) relationships among minors.
