An XL bully has escaped after it killed another dog and injured a woman at a beauty spot in Lancashire.
The hunt for the dog launched after it attacked a Staffordshire bull terrier and his owner in Waterfoot, Rossendale.
The XL bully has been on the run since Wednesday afternoon after the attack on a path off Burnley Road East, around 20 miles north of Manchester.
Alfie, the Staffordshire bull terrier, died of his injuries after being mauled by the XL bully.
The woman walking Alfie was left with an injury to her hand which is not thought to be serious.
When the attack happened, the XL bully was with its owner who left the scene with the dog, the MEN reports.
Officers were alerted at about 2.38pm the same day.
A 29-year-old man from Rossendale was arrested on suspicion of allowing a dog to be dangerously out of control on Saturday. He was released on bail pending a further investigation.
Now the force has released footage of the XL bully, showing a beige and white animal with a red or leather collar.
Lancashire Police launched an appeal as efforts are continuing to locate the XL bully.
A spokesperson said: We would ask anyone with information on its whereabouts or anyone who witnessed the incident on Wednesday to contact the police.
Since the end of January, the breeding, selling, advertising and rehoming of XL bully dogs was made illegal by the Conservative government.
Under the legislation, it also became an offence to own an XL bully unless it was registered and it is compliant with the requirements.
The legislation was brought after a string of deadly attacks last year linked to suspected XL American bully dogs.
In August, Nicholas Glass, 32, was found dead in Rubery, Birmingham after he was mauled to death by four dogs, including two XL bullies.
