A 21-year-old homeless man has admitted raping a dog walker at knifepoint in a Melbourne park, before the victim was able to fight back and stab her attacker. Tyler Skerry faced a charge of rape and theft over the attack when he appeared in Melbourne Magistrates Court today. He spotted his 32-year-old victim walking a dog near Mayer Park in Thornbury in October last year. He knocked the woman to the ground and pinned her down before raping her. But she fought back. Skerry also stole the woman’s $750 mobile phone and went to a house in Preston after the assault. He told the residents he had been hurt in a bicycle crash. He then had a shower, washed his bloody clothes and the next day sold the phone for $80. On October 21, he was arrested and charged over the sex attack.
