Good Samaritan dies along with another man on M1 motorway

Two people have died in what police have described as a "serious incident" on the M1 in Hertfordshire.

One man fell from the Bucknalls Lane bridge over the M1 on Thursday morning.

A Good Samaritan driver who came to his aid was then killed by a passing vehicle.

The motorway was shut for several hours but has now reopened.
