Detective Constable Dale Morris, from the Bedfordshire, Cambridgeshire and Hertfordshire road policing unit, said today (January 10): “Our enquiries have uncovered dash cam footage of two people who were in the area at the time and we are hopeful that they may be able to assist the investigation.

“I would like to make clear that they are not suspects in any way but were simply pedestrians walking by.

“Do you recognise the people pictured? Are you one of the people in the photos?

“If you can help, please get in touch straight away by emailing me at Dale.Morris@herts.police.uk.”
