A spokesperson for Merseyside Police told the ECHO : "This was not a criminal offence as the money was handed over.
"Leaflets have been handed out in the area in order to prevent this happening to others."

"On one occasion, an elderly person has handed money over to the male at which point he has made off possibly in a white van. "
Officers advised residents to 'take a moment to think' before parting with information or money when receiving callers such as this as only criminals will rush or panic you
