An Altrincham school has released a statement after Greater Manchester Police arrested a man following a report of historic sexual abuse.
The alleged offences relate to an incident in the early 1980s, when the victim was 17 years old and a pupil at St Ambrose RC College at the time.
"We are deeply concerned by the allegations and are cooperating fully with the police investigation.
"We note that the police have confirmed that no current teachers are involved and parents should have no undue concern.
"We have contemporary and rigorous child safeguarding policies, which we adhere to strictly and take extremely seriously.
"Our thoughts are with those who have made the allegations - but we can not comment further at this point."
The 63-year-old man was arrested on suspicion of indecent assault and possession of indecent images on Friday 9 November 2012 and has been bailed until 12 March 2013, pending further enquiries.
Police have subsequently received further reports of incidents of historical sexual abuse at the school dating allegedly involving staff.
