A third person has been arrested over the death of Elle Edwards, who was shot dead at a pub on Christmas Eve.
Merseyside police said a 31-year-old man from Tranmere had been arrested on suspicion of conspiracy to murder. He is in custody, where he will be questioned by detectives.
Edwards, 26, was celebrating Christmas with friends at the Lighthouse pub in Wallasey Village when she was fatally shot just before midnight on 24 December.
The beautician was an innocent bystander in the attack, which also left a 28-year-old man fighting for his life and three others hurt.
The force has been given more time to question a 30-year-old man from Tranmere, arrested on suspicion of murder and attempted murder, and a 19-year-old woman from Rock Ferry, Wirral, arrested on suspicion of conspiracy to murder and they both remain in custody.
Police have renewed their appeal for information about the shooting as they attempt to trace the gun used in the attack.
Ian Critchley, deputy chief constable, urged people to contact the police if they know who was responsible for “pulling that trigger in the most indiscriminate, most appalling way” and “anybody who knows where the weapon is, anybody who has harboured or has any information at all. We still want to hear from them.”
Critchley said investigators were working “round the clock” to work out what happened before, during and after the attack.
He said: “We have made great strides forward but I am appealing for further information.”
Critchley said work was ongoing to establish whether the weapon used in the attack, which injured four men, could be connected to any other incidents.
