Police found no violations of Russia’s gay propaganda laws in confiscated children’s drawings from a school art exhibition after parents complained that they depicted same-sex couples.

Russia outlawed “homosexual propaganda” among minors in 2013, a move that allowed courts to ban gay pride events and led to a surge in anti-LGBT sentiment. In November, police in Russia’s fourth-largest city of Yekaterinburg seized 17 drawings for inspection into gay propaganda.

The Yekaterinburg branch of the Interior Ministry ruled that there were “no elements of a crime,” Interfax reported Wednesday.
