A pensioner believed to have been killed by an "out of control dog" has been named by police as 79-year-old Clifford Clarke.

Mr Clarke was in the garden of his home in Clubmoor, Liverpool, when the dog attacked just before 8.40pm on Saturday night, police said.

Two women have been arrested in connection with the death.

Officers found Mr Clarke lying on the ground with the out-of-control dog nearby and called in an armed unit to shoot the animal, a Merseyside Police spokeswoman said.

"When they arrived, officers found the body of the man and they were confronted by a dog that was out of control," she said. "Armed officers attended at the scene and the dog was destroyed. At this stage the breed of the dog is still to be established."

A post-mortem examination is due to take place to establish the cause of Mr Clarke's death.

Crime Scene Investigators were carrying out forensic examinations at the scene of the attack on Sunday, at Richard Kelly Close in Clubmoor, a small cul-de-sac over the road from a public park.

The force said two women, aged 27 and 28, were arrested on suspicion of an offence under the Dangerous Dogs Act, 1991.

That section of the Act relates to an owner or a person in charge of the dog allowing it to enter a private property where it is not permitted to be and the animal then injures a person.

In March a 14-year-old girl died after she was attacked by a pack of dogs at a house in Greater Manchester. Jade Anderson was savaged by up to five dogs at a house she was visiting in Chaucer Grove, Atherton near Wigan. The animals were shot by police.
