The school was graded as "outstanding" by Ofsted
The head teacher of a Roman Catholic school in west London has been suspended while police investigate an allegation of expenses fraud.
Paul Patrick, 53, the head of Cardinal Wiseman School in Greenford, was arrested at his north London home.
Mr Patrick must answer police bail later this month, a Metropolitan Police spokeswoman said.
A statement from the school said: "The school is co-operating fully with the police investigation."
Cardinal Wiseman is a comprehensive school with a designated technology, art and humanities college.
The school was graded as "outstanding" by Ofsted in January and received positive feedback from the Catholic Diocese of Westminster in March.
The Met spokeswoman said Mr Patrick was arrested in April.
"Officers from the Met Fraud Squad arrested a 53-year-old man at his home address in Southgate on suspicion of expense fraud," she said.
Mr Patrick must answer police bail later in June
"He was taken to a west London police station and bailed to return pending further inquiries at a date in June."
The school said: "We can confirm that the police are carrying out an investigation into alleged administrative irregularities at the school."
It added: "Cardinal Wiseman has consistently maintained excellent results.
"Our priority remains to ensure the welfare and education of all our pupils."
An Ealing Council spokeswoman said: "We can confirm that a member of staff at Cardinal Wiseman School is assisting police with an investigation into alleged administrative irregularities and has been suspended by the governing body."
The Roman Catholic Diocese of Westminster did not comment.
