A teenager has been charged after allegedly chasing a little girl in a park before grabbing her sister around the neck.
Kyle Torrance Duncalf, 19, allegedly terrorised a young family at the Des Penman Reserve, in Perth’s suburbs, on Friday night.
Dog walker Matthew Horgan said he leapt into action after hearing screams and witnessing a girl running away from a grown man.
Duncalf allegedly chased a girl who is under the age of 15 before assaulting her younger sister and grabbing her neck.
Bystanders called triple 0 and when police arrived the teenager was arrested and taken into custody.
Mr Horgan claims Duncalf had been speaking incoherently and was shouting threats.
It was the family’s first trip to the park after having only recently moved to the area.
The dog walker said they were traumatised after the incident.
‘They were pretty shaken up. They were crying, the mum was in shock — I’m so glad the police arrived as soon as they did,’ Mr Horgan said.
He praised other bystanders who jumped in to help after witnessing the alleged attack.
Western Australia Police described the attack as a ‘serious incident’.
Duncalf was remanded in custody after appearing at Perth Magistrate’s Court on Saturday.
The 19-year-old was charged with attempted murder and aggravated deprivation of liberty.
He is facing a maximum penalty of life imprisonment.
Duncalf will return to court on Monday.
