Detectives investigating the murder of Elle Edwards have received multiple tip-offs about "individuals and wider tensions", according to Merseyside Police.
The force thanked the public for providing "nearly 150 pieces of intelligence" about the Christmas Eve shooting, at the Lighthouse Inn in Wallasey Village. Merseyside Police said critical information, including CCTV footage, had been passed to detectives either directly or confidentially via Crimestoppers.
The killer opened fire shortly before midnight, fatally wounding popular 26-year-old beautician Elle and also leaving four other men, aged between 22 and 33, with injuries. Since then three people have been arrested, including a 30-year-old man on suspicion of murder and attempted murder. He has since been released under investigation, but also recalled to prison for breaching the terms of his licence.
