A man has been arrested on suspicion of murder and attempted murder after a pensioner believed to be his grandmother was stabbed to death and a nine-year-old boy was injured in Shipley, West Yorkshire.
The woman, named as Louisa Denby, 84, was found dead from 'numerous stab wounds' at her home.
Police attended the address investigating reports that the boy had been stabbed in the nearby Carnegie skate park, part of the Windhill recreation ground, yesterday afternoon.
Det Insp Lisa Griffin said she believed the incidents were linked.
"The nine-year-old boy was out playing and was returning home for a drink when he was approached by a male and with no prior warning and for no reason known to us at this time he was attacked with a knife - a single stab-wound causing him injuries to his chest and his arm," she said.
"Ten minutes after that attack an eight-year-old girl was chased through her garden at home. Nothing untoward happened to her.
"As the inquiries continued in the afternoon and evening yesterday, we were taken to an address on Prospect Mount where we discovered the body of an 84-year-old woman."
The boy was airlifted to Leeds General Infirmary after being stabbed in the chest and arm in broad daylight in what has been described as a 'shocking' attack.
Local councillor Hawarun Hussain claimed the incident had alarmed the local community, and said the skate park is a new addition to the area.
"At no point do you ever think that your child is going to go to the skate park and get stabbed. It's just not expected," she said.
"The skate park is relatively new. It was the kids who wanted it. "It was meeting the demands of the children wanting a skate park where they could go and be safe and enjoy themselves."
The boy is said to be in a stable condition but is expected to undergo surgery today.
