A video taken from the queue outside of the Elland Road away end of Saturday shows the issues Newcastle United fans had getting into the ground.
Several hundred fans missed kick-off due to congestion at the turnstiles - with fans claiming as little as four turnstiles were in operation for nearly 3,000 fans.
This video above, sent into Chronicle Live, shows the turnstiles not accepting tickets and tensions rising at the lack of information and clarity from stewards.
As the camera pans around the scale of the issue becomes apparent with fans tightly packed together in what looks like chaotic scenes.
Chronicle Live has spoken to several fans who caught up in the incident - with some fearing a fatality.
West Yorkshire Police said in a statement: "We are aware of issues at the Leeds United v Newcastle United game at Elland Road on Saturday that resulted in congestion at the entrance points for away fans.
"We are currently liaising with the club to review the circumstances."
Leeds United also provided a statement: "The club acknowledges the complaints raised by some Newcastle United supporters regarding issues experienced entering Elland Road on Saturday.
"Leeds United will now work with the Newcastle Supporters Trust, West Yorkshire Police and our own safety team to review the issues raised and ensure we continue to provide a safe environment for everyone attending our stadium. We will not make any further comment until a review is complete."
