Dunedin police sergeant Aaron Burgess has told Checkpoint there has been another incident of a student falling during St Patrick's Day partying.
"We've just had another incident where an intoxicated student has just fallen off a balcony and injured themselves quite severely."
He said they fell backwards off a second storey balcony and landed on their back.
They were unconscious for some time, he said. Burgess said there has been rain today, making roofs slippery.
It comes after another student fell off a roof on Castle St, earlier on Thursday.
