Police are appealing for information over the attempted robbery, which took place in an alley in the Liscard area of Wirral.

He suffered a cut to his hand that has since required hospital treatment.

Detective Inspector Emma Kerrigan said: “This was an appalling incident for the victim to have experienced, and he is receiving the full support of officers.
