A 30-year-old man is in custody on suspicion of the murder of Grimsby man Peter Craven.
As previously reported, independent charity Crimestoppers were offering a reward of up to £5,000 for information relating to the murder of the 48-year-old.
Police previously said they were keen to speak to Michael Kavanagh, who still has links to Grimsby, in connection with the incident and he was arrested during the evening of Saturday, October 27 on suspicion of murder and section 18 grievous bodily harm.
Kavanagh, of no fixed abode, has been charged with intent to cause grievous bodily harm and possession of an offensive weapon in a public place.
He is due to appear before Grimsby Magistrates Court on Monday, October 29.
Emergency services attended a property at Oxford Street in Grimsby at around 11.40pm on August 15 after reports that Peter was seriously injured and he was later pronounced dead at the scene.
A post mortem revealed that he died following a serious head injury.
After arresting Kavanagh Humberside Police said: “He is a wanted man who we have been appealing to you for your help in finding him in connection with the death of Peter Craven in Grimsby.
“We’d like to thank you for your help with our appeal. We have named Michael Kavanagh in the interest of public safety. He is now being questioned.”
