Police submitted records in connection with the case to the Budapest prosecution as suspicion of involvement of off-duty police officers has been raised, they said.

Speaking to commercial television channel RTL Klub on Monday, a woman said that her daughter sleeping in a tent in the park had been kicked twice in the kidneys by an unknown person.

She told later news portal index.hu that as an unidentified person kicked the tent during the night she shouted that there was a girl sleeping inside.

The perpetrator then delivered another kick shouting that “this is how the Liget must be protected!” the woman added.

The daughter has not suffered any serious injuries, the portal said, citing a hospital report.

Environmentalists have been protesting for months against the project which they fear would ruin the popular public park.
