A MAN hit a police dog with a metal pole on a beach just hours after scratching expletives across a former friend's car, a court was told.

Joseph Duncalf, 25, of Duddon Road, Askam, struck police dog Bronn with the weapon on Askam beach on April 19, after the German shepherd was instructed to "hold him" by its handler, PC Glenn Myerscough.

Officers had been called following concerns for Duncalf's welfare. However, after they arrived at the scene, he made several threats towards them with the metal bar, including saying: "you're going to get this in your head".

Bronn bit Duncalf by the abdomen but was then hit on the head, causing bruising and requiring a visit to the vets.

Furness Magistrates' Court was told on Tuesday that Duncalf, who has a history of mental health problems, had gone missing and was located on the beach by police.

Mr Andy Travis, prosecuting, said: "Bronn has moved towards the defendant and takes a hold by the abdomen. The defendant has then attacked Bronn several times to the head.

"Police used the Taser as the defendant has managed to free his arms on many occasions while being handcuffed."

After arresting Duncalf, it emerged that he had become upset after believing his former friend was seeing a woman he had had a relationship with previously. 

The defendant had posted a "small essay" on Matthew Postlethwaite's Facebook page, telling him "your car looks really class".

Mr Postlethwaite then discovered his Volkswagon Golf had an expletive carved into its metalwork, causing £500 worth of damage which Duncalf has since paid back.

Duncalf pleaded guilty to two charges of criminal damage and one charge of possessing an offensive weapon in public.

Mr Mike Graham, defending, said: "He had it in mind the owner of the vehicle had involved himself with a young lady he had previously done. He was annoyed by that. 

"He is approached by four police officers and a police dog. He said all the officers were shouting at him and the dog was barking.

"The noise, in his words, was very loud in his head.

"He's sorry for what's happened."

Magistrates imposed a curfew for eight weeks on Duncalf, requiring him to be at home between 9pm and 7am.

He was also ordered to pay £30 towards Bronn's veterinary bill, a victim surcharge of £85 and court costs of £85.
