'No police cordon was thrown around the Mulberry Bush pub before an IRA bomb went off inside, despite officers responding to a coded warning in the building, an inquest heard.
Jurors at hearings into the 1974 Birmingham pub bombings were told there was no evidence of attempts to clear the premises or its immediate area, in spite of an 8.11pm warning call pin-pointing the iconic Rotunda where the pub was located.
Two blasts then ripped apart the Mulberry Bush and the nearby Tavern In The Town, between 8.15pm and 8.20pm, on November 21.
The jury heard how casualties were 'crawling over bodies' to escape the devastation within the Mulberry Bush, on the ground floor of the Rotunda.
On Friday, it also emerged that some of the police logs detailing the immediate responses on the night of the incident were still missing.
Inquests at Birmingham Civil Justice Centre into the 21 victims killed in the blasts got under way this week after a 44-year wait for the bereaved families.
Opening the proceedings, coroner Sir Peter Thornton QC told jurors they would hear evidence of how the two bombs ripped apart two pubs on what was a 'perfectly ordinary evening'.
The devices, detonating in 'massive explosions' just minutes apart inside the pubs brought 'devastation', jurors heard.
Earlier this week, jurors were told how police numbers had been cut to just 15 officers across 'busy' Birmingham city centre, that night.
Other officers had been drawn away to provide security for the funeral transportation arrangements of IRA bomber James McDade, at Birmingham airport.
On Friday, Anthony Mole - an ex-counter terrorism police commander with 30 years' police experience - continued giving expert evidence to the inquest, and was asked about whether he had seen any evidence of a cordon.'
