The man then attempted to stab her.
“I wrestled with him and he punched me several times in the torso.”
Whanganui police Detective Neil Forlong confirmed police were investigating the assault and said he applauded the woman’s willingness to help a person who appeared to be injured or unwell.
“We all should do that if we can, but caution is always advised in a situation like that.
“You need to think about your swimming ability before diving in the water.”
The woman said the man ran off in the direction of Kaikokopu Rd and he had disappeared by the time the police arrived.
She said her attacker was a large man with a tanned complexion weighing around 140 kg. He was wearing a black cap, a red hoodie, black jeans and boots.
Forlong said police were investigating the incident and requested that anyone who might have seen the man make contact.
