A detective inspector has renewed an appeal for information as police continue to investigate the murder of a Lancaster man in July.
Det Insp Adie Knowles said police are continuing to "progress every line of inquiry" after the death of 50-year-old Damian Jackson.
Mr Jackson was found dead in his flat on Regent Street in Lancaster on Tuesday July 25.
A post-mortem established that he died of multiple injuries and police said he had been violently attacked.
His last confirmed sighting was in Aldi supermarket on Aldcliffe Road, near his home, on the Sunday morning of July 23.
Below is a CCTV image of Damian at the supermarket.

"There is a dedicated team still very much investigating," said Det Insp Knowles, speaking on his regular Beyond the Beat segment on Beyond Radio.
"This is a further appeal that if anyone knows anything, and you haven't already spoken to police, then get in touch with us.
"I would like to reassure the public there is a team trying to put their foot down to progress every line of inquiry."
In a statement, Mr Jackson's family said: “The whole family is beyond devastated at the loss of our beloved son and brother.
“Damian was humble and gentle, well loved by many across Lancaster, with a great sense of humour. He is much missed by us all and his death has left an enormous hole in our lives.”
Please contact police if you saw anything unusual or suspicious in Regent Street or the surrounding area between Sunday July 23 and the morning of Tuesday July 25.
Anyone who has dashcam footage from the area between those dates, is asked to contact police too.
You can call police on 101 – quoting log 0535 of July 25, 2023 – or call the freephone Crimestoppers line on 0800 555111 or visit local police stations in person.
