Superman spotted in Serbian sky

Serbian authorities are investigating reports of a real-life Superman people claimed to have seen flying over their houses.

Hundreds of residents in Ljubovija described seeing a cloaked person flying above buildings "as if he had an invisible engine on his back" and changing directions while in mid-air, local daily Blic reported.

One local said: "It was like something out of Superman or Batman. No one has any rational explanation for what we all saw."

Police in the town have refused to comment, ANANOVA.com reports.
