A bursar jailed for dishonesty committed at a top Birmingham school has been condemned as "an accomplished conman" after it emerged he obtained another senior job by using "an intricate web of deception".

Andrew McCallum left Hallfield Independent School, in Edgbaston, last October for personal reasons but soon afterwards police were called in to investigate allegations of false accounting.

In the meantime, and unknown to Hallfield, McCallum used a string of forged references to land a similar post at Norwich School, another independent institution. He started work there in March but resigned on July 21 when that deception was uncovered.

Eight days later, McCallum was sentenced to eight months imprisonment after pleading guilty at Birmingham Crown Court to false accounting.

Hallfield headmaster Clive O'Donnell said they were unaware of McCallum's activities after he left them. The school has refused to disclose how much it lost because of McCallum's dishonesty except to say it was "significant".
