An embarrassed postie drew crowds after unwittingly setting off a security alarm in his van.
The man was on his rounds at Edge Hill University when he accidentally became locked inside his van with sirens sounding at 10.30am.
He was trapped for more than an hour, while the alarm repeated: “Help, help, vehicle under attack. Please call the police.”
Students gathered to take photographs and videos of the van.
Lancashire Constabulary confirmed it had not been alerted.
The Royal Mail have been contacted for a comment.
