DETECTIVES have made two more murder arrests as they investigate the stabbing of a man in his own home.

Mark Fisher, 33, was found with fatal stab wounds in his property in Edleston Street, Accrington, at 1pm on Sunday.

Police have this morning confirmed that a 33-year-old woman and a 45-year-old man, both from Accrington, were last night arrested on suspicion of Mr Fisher's murder. They are currently in custody.

It comes as a 37-year-old man, from Accrington, arrested over the weekend on suspicion of Mr Fisher's murder has been released without charge, while a 35-year-old woman, from Accrington, arrested over Mr Fisher's death has been released under investigation pending further enquiries.

Detectives have also confirmed that a Home Office post mortem examination has since given a cause of death of multiple stab wounds.

Detectives are continuing to probe the circumstances of Mr Fisher’s death and are carrying out CCTV enquiries, house to house enquiries and other lines of investigation.

They are appealing for any witnesses or anyone who may have information to get in touch.

Detective Chief Inspector Jill Johnston, who is leading the inquiry, said: “Our thoughts very much remain with Mr Fisher’s family and friends at what is an extremely traumatic time.

“I have a team of detectives and staff working on this investigation and I would like to stress that we are continuing to work around the clock to establish exactly what happened. While we have made a number of arrests, our enquiries are ongoing.

“I would appeal for anyone who has any information which could assist us to come forward if they haven’t already. Even if you think the information you have is insignificant please get I touch and let us be the judge.”

In a tribute Mr Fisher’s family, who are being supported by specially-trained officers, said: "As a family we are heartbroken. Mark was much loved by all of his family and we miss him so much. We desperately need to know what happened to Mark and would appeal to anybody that knows anything to contact the police.”

Yesterday police moved to dispel rumours that Mr Fisher was a registered sex offender. That followed a number of comments on social media, which officers said had caused upset to his family.

Anyone with information should contact police on 101 quoting log number 0684 of Sunday, January 19, or independent charity Crimestoppers on 0800 555 111.
