A third person has been arrested in connection with the murder of Elle Edwards, who was shot dead outside a pub in Merseyside on Christmas Eve.
A 31-year-old man is being questioned over the killing, Merseyside Police have said.
Ms Edwards, 26, was not the intended target when shots were fired outside the Lighthouse Inn in Wallasey Village in the Wirral at around 11:50pm.
A man aged 30 from Tranmere has previously been arrested on suspicion of murder and attempted murder, and a woman aged 19 from Rock Ferry has been arrested on suspicion of conspiracy to murder.
Police said on Wednesday they have had “some tremendous intelligence” but are still searching for the gun that killed Ms Edwards.
Forensic officers remained outside the pub on Wednesday and a cordon was still in place outside part of the pub and its car park.
