Hillsborough disaster survivors 'threatened by police'

Survivors of Hillsborough have said they were intimidated and threatened by police from the independent force asked to investigate the football disaster.

BBC Newsnight has heard that witness criticisms of police who had been at the scene were not properly recorded.

This is the first time fans have come forward to question how West Midlands police took their statements.

The force declined to comment pending ongoing inquiries and the forthcoming inquests into the deaths of 96 fans.
