Police are hunting for a gunman after a woman was fatally shot at a pub on Merseyside on Christmas Eve.
Three other men are being treated for gunshot wounds in hospital after the attack in The Lighthouse in Wallasey Village, Wirral at about 23:50 GMT on Saturday.
A number of other people were also injured, police added.
Officers are appealing for information after the gunman fled in a dark vehicle, believed to be a Mercedes.
Merseyside Police said the woman died after she was rushed to hospital following the shooting, which happened in a “busy venue full of young people”.
The incident was described as “despicable” by Chief Constable Serena Kennedy and “heartbreaking” by the area’s MP, Dame Angela Eagle.
Det Supt David McCaughrean said: “We have a number of officers at Wallasey Village who are carrying out extensive inquiries to understand exactly what has taken place and take immediate action.”
The woman’s family has been informed and is being supported by specially trained officers.
In a statement, The Lighthouse pub said they were “completely shocked”, adding: “This is a tragedy beyond any words.
“All our thoughts are with the friends and family of our customers and in particular our hearts go out to the family of our customer who has lost her life.
“We have provided the police with CCTV footage and our priority is supporting everyone who has been impacted.”
A spokesman said anyone who had Christmas Day bookings were being contacted and given a refund.
