Police are appealing for information after a couple in their 60s were assaulted in Chorley.
Between 9.30pm and 10pm on Sunday, the husband and wife were walking home along Park Road after a night out.
A man and woman crossed the road opposite the Astley Park gates, approached the couple and demanded to know why they had called them names.
The male offender tried to punch the man, but none of the punches connected.
His female companion and the 66-year-old man’s wife stepped in to try and prevent the him punching the man, with his wife asking them to go away.
The woman asked the couple to go, stating her grandfather had died that day.
The man grabbed the 64-year-old woman by the arms and pushed her to the ground, causing her to end up in the road.
The 66-year-old man tried to help his wife up, when he was also shoved into the road.
The man and his female companion then ran off, possibly through Astley Park.
