Deputy District Judge Kelvin Henderson sent the case to Kingston Crown Court.
He said: 'This charge is one that can only be dealt with at the crown court.'

In June, the rugby ace was convicted of drink-driving after getting behind the wheel having spent the night drinking cocktails and champagne.
He was found guilty of the offence following a trial at Westminster Magistrates' Court and ordered to pay a total of £7,620 in fines and costs. He was also banned from driving for 18 months.
The rugby union player claimed he was 'shocked' that the breathalyser was positive, despite admitting he had drunk two espresso martinis and a glass of champagne less than an hour earlier.
