A woman has been left with potentially life-changing injuries after being attacked by a dog in Lancaster.
The victim, a cyclist in her 40s, was taken to hospital with serious leg injuries after the animal stayed latched on to her for several minutes before she broke free.
Police were called at around 4.20pm on 5 May by paramedics who were treating her for her wounds.
She was cycling with a friend on a cycle track behind the Priory Church, close to the Millennium Bridge, on 5 May and had to brake to avoid a woman and child, according to police.
They were later approached by a man, who had two brown Staffordshire bull terrier or bullmastiff-type dogs and accused them of almost knocking into his child.
Police said he slapped one of the dogs on the head, causing it to bite the victim on the upper leg and stay attached to her for several minutes before she broke free.
The woman, who is from Morecambe, was taken to Royal Lancaster Infirmary and has since been discharged.
Police are appealing for information, as they seek to identify the dog walker.
He is described as white, 5ft 9-10in, slim, with brown short back and sides hair.
Police believe he is in his early 30s and was not wearing a top.
PC Richard Hannaford, of Morecambe Police, said: "This incident has left the victim with a very serious injury.
"As part of our ongoing inquiries, we need to identify and speak to the man who was walking the dogs. I would urge anybody who knows who he is - or the man himself - to contact the police as soon as possible.
"Similarly, I would ask any witnesses or anybody with CCTV, dashcam or mobile phone footage which could assist our investigation to please get in touch."
