Sheriff Derek Livingston said: “In my view you richly deserve a custodial sentence today.”
He placed Houston, 5 Acacia Avenue, Brentford, on a supervised community payback order for two years with the condition he complete 300 hours of unpaid work within 12 months.
He was also placed on the sex offenders register for five years and made subject to a non-harassment order not to enter the street where he committed the offence or contact with the victim in the case for the next two years.
Houston’s case and court orders were transferred to London.
