POLICE are still investigating whether the dog which killed a schoolboy in Caerphilly earlier this week was a banned breed.

The animal was shot seven times by armed officers after it launched the attack.

Jack Lis, 10, died on Monday, November 8, after being attacked by the dog at his friend's house in Penyrheol, Caerphilly.

Police say a dog legislation expert has now been brought in to examine the dog's features to see if it is a breed allowed in the UK.

Speaking at Blackwood Police Station earlier today, chief superintendant Mark Hobrough said the the investigation into the legality of the animal was ongoing.

"It's a process which is done thoroughly, by expert witnesses," he said.

"As soon as we have got that information we will release it."

The dog had only been with Jack's friend's family for days, after being sold by roofer Lee Jenkins.

Mr Jenkins advertised as being "grate [sic] with people."

The advert described it as height 24ttw - about the same as a Labrador - and weighing 115lbs.

Neighbours described the animal as having "huge muscles" protruding from its shoulders as they saw it moments after Jack's death.

Mr Jenkins said: "I am not the owner of that dog.

"I told the police everything I know. They know I have nothing to do with it."

Chief superintendant Hobrough said: "The original dog owner has been assisting us with enquiries and our investigation.

"That will continue to be the case."

The family of 10-year-old Jack Lis paid tribute to him earlier today.

“We are absolutely heartbroken. Our lives will never be the same without Jack," they said.

“He's forever in our hearts.

"Sweet dreams Jack, our perfect boy.”
