A Royal Navy seaman has died after he was attacked on a night out in his home town of Liverpool.
Anthony Cavanagh, 22, died on Wednesday, two weeks after he was attacked in the Walkabout bar in the city centre while on shore leave.
Mr Cavanagh, who served on HMS Cardiff, was attacked by one of three men after accidentally bumping into one of the group, Merseyside Police say.
Officers want anyone with information about the attack to come forward.
Mr Cavanagh was targeted by the three men as he walked though the bar with friends in the early hours of 24 September.
One of them threw a drink over him and then a punch was thrown.
Merseyside Police said Mr Cavanagh was unconscious from the moment he was hit.
Det Ch Insp Paul Richardson said: "Anthony was out to enjoy himself with friends and was due to return to his ship on the Monday.
"He didn't go out looking for trouble and his family are devastated at the loss of their son and brother."
The man who attacked Mr Cavanagh was white and muscular with short brown hair. He was wearing a white T-shirt and hooded top.
A spokesman for the Royal Navy said Mr Cavanagh was "very popular, hard-working and professional".
He added: "Despite having visited many foreign destinations around North Africa, South America and the Caribbean, he missed being away from Liverpool, his family and his friends, and returned home to visit as often as he could."
