A man has reportedly fallen through a skylight while allegedly trespassing at a southwest Sydney school.
The man, aged 22, is being treated at Liverpool Hospital for a fractured nose and jaw, as well as damage to his teeth.
Fairfield police were called to Mary Mackillop Catholic College in Wakeley after 1.30am when security guards discovered a smashed window and blood on the ground, according to the Daily Telegraph.
The man is understood to have been with two other men walking along the building's roof before he fell through the skylight.
All three men are expected to be charged with trespassing.
