This is the moment a double murderer was arrested on the M5 near Worcester.

Stephen Alderton has today been sentenced to life in prison after murdering a father and son over a family court case involving his grandson.

Alderton shot the two men with his Beretta shotgun on March 29 this year, two days after a family court hearing.

The 67-year-old killed Joshua Dunmore, 32, and his 57-year-old father Gary Dunmore in two villages Cambridgeshire, and was later found by police on the motorway near Worcestershire.

In the video, West Mercia Police officers can be seen telling Alderton to get out of his vehicle, to move forward with his hands in the air and then to get on the ground.
