Hundreds of people living in flats near Anlaby Road became trapped as armed officers responded to a "cracking noise" coming from one of the buildings.

The incident, which started at around 9pm on September 22, saw police close off Anlaby Road between Ferensway and Park Street, as well as surrounding roads including Cambridge Street, Pease Street and St Lukes Street.

Around 20 customers also became trapped in a nearby pub as armed officers told them to "get in" and "get away from the windows".

A spokeswoman for Humberside Police said the call came from a member of the public who believed the noise "could be shots fired from the building".

She said: "Armed officers have been in the Anlaby Road area of Hull this evening following a call from a member of the public at around 8.50pm, reporting a cracking noise which they believed could be shots fired from the building.

"Officers were immediately deployed and enquiries were undertaken at the scene. A police cordon and road closures were in place, and people were asked to avoid the area as a safety precaution whilst this was carried out.

"There have been no further reports received and no injuries reported, with no suggestion there is any connection to terrorism or known criminality."

Chief Superintendent Darren Wildbore said: "Enquiries will continue however there is not believed to be any wider threat or risk to the public at this time.

"We will always take any report of this nature seriously and respond appropriately, as the safety of the public and ensuring their protection will always be our priority."

One woman, whose mum lives in one of the flats nearby, said her mum had heard what she thought were "gunshots" before watching the scene unfold.

"All I know is she is stood watching from one of top floors, armed police not letting anyone in or out," she said.

"They're positioned towards the flat doors. We don't know what's happening."

Another woman, who lives in one of the high-rise flats, said she had heard "a few bangs" before going to her window and seeing police arrive in the street outside.

She said: "Police got it cordoned off really fast then seemed to have a lot of other streets cordoned off too."

She said she had seen armed police and the dog squad in and around Cambridge Street, with officers appearing to prevent people from entering or leaving nearby blocks.

An arriving ambulance had been flanked by police, she said.

"I'm scared because I don't now if the person who has done it is in the Cambridge Street flats," she said.
