VIENNA (Reuters) - A man has escaped from his Austrian jail cell by squeezing through a food hatch in the door, police said on Wednesday.

The 19-year old Kosovan, who weighed less than 121 pounds, was being held at the prison in Linz for entering the country illegally, police spokesman Alexander Niederwimmer told APA news agency.

How he got through two further doors or possibly over the prison wall is being investigated, said Niederwimmer, calling the escapee "a snake man."
