A day after the massage parlour incident, police said a 14-year-old boy robbed an Alexandra St store in Hamilton.
Mr Smith said police arrested the boy yesterday.
"Inquiries revealed that shortly before the robbery this offender had withdrawn cash from an ATM using stolen cards so he was charged with using a document for pecuniary advantage and aggravated robbery.
"He was also charged with possession of a knife and cannabis after these items were found on him when located."
The boy appeared in the Hamilton Youth Court yesterday and was remanded until April 29. He was also referred to Youth Aid.
Mr Smith said both incidents were traumatic for the victims.
