Greater Manchester Police launched a murder investigation after officers were called to the Georgia Brown's pub in Hindley, Wigan, shortly after 11.30pm on Saturday to reports a 51-year-old man had been assaulted.

"My thoughts are with the man's family at this devastating time. Our specialist support officers are with them to support them.
"Whilst we are not searching for anyone else in connection with this incident, we are appealing for witnesses to come forward to let us know what they saw.
