Responding to the publication of a report by the Police Investigations and Review Commissioner on Police Scotland's failure to act on a request for assistance, in an incident that later became a murder enquiry, Scottish Liberal Democrat justice spokesperson Liam McArthur MSP said:
"This is a terrible tragedy.
"Bilston Glen was at the centre of the response to the M9 incident. Officers, staff and the public will be horrified to learn that it's processes have so tragically failed once again.
"The public will expect an urgent response from Police Scotland. It's procedures must be strengthened so that all decisions are informed and make use of the range of information available to the national force."
