A police spokesman said: "At first he seemed very confused but quickly turned aggressive and shouted abuse at the officers before trying to run off.

The pair were taken to hospitals in the nearby Slovakian capital of Bratislava and the girl was discharged shortly after, thankfully with nothing more than a few scratches.
