A man was attacked as he delivered groceries in Yaxley near Peterborough.
The 40 year old was by his van in Landsdowne Road, at about 7.30pm on Tuesday (January 29), when the men approached him.
They demanded the van keys and his wallet.
The victim told them to go away, but as he turned back to the van they closed the door on his arm causing serious injuries. Nothing was taken during the incident.
The men were white, aged between 16-20. One spoke with a foreign accent.
