Officers have released a hair-raising video of a violent burglary in Scunthorpe in a bid to catch those responsible.
A 42-year-old can be seen on the footage putting tools in his van when he is attacked from behind.
Shortly after, another man appears to kick and punch the victim before he is dragged out of the van and down an alleyway.
Humberside Police are investigating the burglary on Stockshill Road in Scunthorpe just after 8pm on April 16, 2018.
Detectives said they have carried out a number of enquiries and made arrests in connection but haven’t been able to charge anyone.
The victim was left with life-changing injuries and gave permission to release the video to try and get justice.
He said: “I just want justice. I don’t know who did it and I don’t care what their reason was. I just want justice.
“What happened that night still affects me. I suffer from flashbacks and depression and I am constantly looking over my shoulder.
“It’s had a huge impact on me, my life and my livelihood. I lost my sight in my right eye and I was in pot for 11 months because of injuries to my arm.
“I just want them locked up for my own peace of mind.”
Four men, aged 46, 31, 33 and 62, have been arrested in connection with the incident and released under investigation.
Two further men arrested in connection with the incident have been released without charge.
Detective Inspector Kerry Bull, who is leading the investigation, said: “This was a particularly nasty assault and while these kind of incidents are rare, we know the impact it they can have on victims and the wider community, which is why we are determined to do all we can to find those responsible.
“We have already made six arrests and it remains very much an active investigation.
“Through our enquiries so far, we believe that those involved in the incident may have links to both the Lincoln area and potentially to Devon and Cornwall and we’re hopeful that by releasing the CCTV of the attack we may reach people who have not previously seen our appeals.
“Someone out there knows who these men are and I want to appeal for those people who do to get in touch.”
