READ: Xavier principal's letter to parents "But if a criminal act occurs it will be investigated by Victoria Police and if criminal offences are disclosed we will be charging the people appropriately.'' Xavier - one of Melbourne's most elite Catholic schools with fees of more than $16,000 a year for VCE students - suspended the entire year 12 group yesterday when end-of-year antics led to one student being taken to hospital amid complaints from neighbours of students' drunken behaviour. Residents who live near the Kew campus said students went on a rampage, harassing motorists and drinking heavily. Police confirmed today that an Argyle Road resident's car was damaged by a group of youths in school uniform.

Acting Senior Sergeant Philips said the roof had been damaged as though someone had been jumping on it. Police said they were investigating whether students from other schools were involved, and were liaising with school officials. "When these people are located, the charges will be criminal damage to the car and there may be some peripheral charges in relation to the behaviour of students (yesterday) afternoon,'' Acting Senior Sergeant Philips said. Guards posted at exclusive school Security guards were posted in front of the exclusive school this morning.

One year 12 student, who did not wish to be identified, told The Age the class of 2008 had "a long history of misbehaviour'' and had been denounced as the "worst year level at Xavier in 30 years''. He said he had not been involved in any of the end-of-year antics and was shocked to learn he had been suspended along with his classmates. The student said when he returned to the school today to discuss an upcoming exam with a teacher, he saw guards posted at the gates and was told that the year 12 students were to be kept out of the school. Trouble after mass suspension Despite the mass suspension, there were further reports of trouble near the school last night.

Police said several emergency calls were received last night and early this morning complaining about "disruptive youths'' on the road outside Xavier College, which boasts the Latin motto of Sursum Corda: 'Lift up your hearts'. Melbourne talkback radio stations were flooded with calls this morning from the public and parents of Xavier College students at odds over the students' 'muck-up day' behaviour. "(They were) throwing bottles everywhere, there were smashed bottles all through the street,'' a Kew resident identified as Chris told Radio 3AW. "This group of unruly boys came down the street, jumped all over my car and have done considerable damage. They got a taxi driver and jumped all over his car. He looked terrified,'' she said. Another woman, identified as Sandy, said a mob of 30 to 40 students was harassing traffic outside Glenferrie station last night.

"Just down from the intersection of Burwood and Glenferrie (there were) multiple boys in black balaclavas punching the (car) windows, punching the windscreen and simulating very vulgar acts,'' Sandy said. A number of students contacted The Age to offer tell-all accounts of muck-up day behaviour in return for a fee. No payments were offered. Police receive multiple call-outs Victoria Police received six calls last night between 6pm and 7pm about youths causing trouble in the Kew area. Another call was made at 2am to report a disruptive group of 30 youths standing on Barkers Road, which runs along the southern boundary of Xavier College.

The manager of a liquor store near the school said there "were a few more young people than normal'' buying alcohol yesterday afternoon. However, students and parents of Xavier College claim the media has over-reacted to the graduation day antics. "I've got a year 12 boy (and) it was a drastic over-reaction,'' said a Xavier College mother who identified herself as Jenny. A Xavier College student called James told Radio 3AW the behaviour did not warrant mass suspension. "The school suspended us all to de-escalate the situation,'' James said.

Paramedics treat teen Loading An ambulance spokesman confirmed paramedics had treated a 17-year-old male who had injured his leg. The youth was taken to hospital with a dislocated or fractured knee.
