A Russian artist has claimed responsibility for a set of shower heads that appeared on the handrails of a Moscow subway car, in a mysterious installation that left metro authorities puzzled.
The artist, who goes by the nickname of Petyok or Petek, said in a letter to Russia's The Village that the shower heads were not an advertising campaign — as some had suggested — but a form of artistic expression, the news portal reported.
The artist also posted a photo on his LiveJournal blog of a shower head with an attachment ring, allowing it to be fixed to a handrail, as well as a video of the shower heads in a subway car.
The shower heads, which appeared on the overheated Moscow subway earlier this month, caused a stir on social networks, with more than 2,300 Facebook users giving a "thumbs up" to a photo of the installation, published by The Village earlier this week.
However, subway authorities appeared less amused.
"That the shower heads really were there is a fact," a spokesperson for the Moscow subway told Moskovsky Komsomolets. "But we can say nothing more. An internal investigation is being conducted."
