Armed police swooped on the Old Bank pub around 8.20pm after reports several shots had been fired.
The terrifying shooting happened in front of staff and regular customers who were sitting inside the pub for the first time since it was closed during lockdown.
Witnesses told the ECHO that a gunman ran through the pub and fired a number of shots before turning to the exit and shooting a man near the doorway during the sickening scenes.
A man in his 20s was found with gunshot wounds to his chest and was rushed to hospital.
Police have since revealed a second man turned up at hospital with a gunshot wound to his groin following the shooting.
The men, who are said to have sustained non life threatening injuries, have both been arrested on suspicion of shooting each other.
Merseyside Police has said the shooting is believed to have been sparked by an earlier altercation but are still investigating.

Today the Old Bank pub on Princess Drive remains a cordoned off crime scene with a mobile police station parked outside.
Officers remain at the scene after Merseyside Police said they will be keeping a high-visibility presence in the area to reassure people as they continue to gather information.
Detective Chief Inspector Matt Smith said: “We understand the concern that such incidents have, especially when taking place in such a public location with other people in close proximity.
"We’re pleased to have arrested two people who we believe were those involved, but nonetheless, I’d continue to appeal for any information which may be vital to this investigation going forward.
“It’s absolutely key that all of those people present come forward, so we have full accounts of exactly what happened.
"If you saw or heard the incident, captured those responsible on CCTV, dashcam or other devices, or have heard anything since, come forward.
"This can be by speaking to those officers in the area today, or via other channels, directly or anonymously."
He added: "The recent decrease in such serious gun crime incidents across Merseyside is testament to the hard work of officers and staff across the force, but also the information from those communities most impacted upon.
With your help, we will keep removing weapons and those who use them from the streets.”
