A Western Australia man has been arrested, accused of trying to car jack several drivers with a stick while naked.

A NAKED man was crash-tackled and hogtied by horrified witnesses after he allegedly tried to carjack several drivers in Western Australia.

WA Police said the man in this mid 20s tried to stop three cars on the Brookton Highway in Karagullen, about half an hour south east of Perth.

Phil Ferraro and his daughter Frankie were driving past when they saw a man trapped in an overturned ute and stopped to help.

He soon realised the driver was the victim of an attempted carjacking — and the alleged culprit was continuing to target other drivers.

“This guy had run out from the bush (and) smashed the (driver’s) windscreen,” Mr Ferraro told Channel 9.

A woman who had also stopped to help was then allegedly attacked by the same man.

“He tried to drag the girl out of her car and carjack her, ripping at her clothes and hair,” he said.

Frankie Ferraro witnessed the bizarre incident unfold right in front of her.

“So on our normal trip to Metro Road with our dirt bikes yesterday, there is a ute on its side on the Brookton Highway, and a guy on the road going mental, covered in blood, there is also a lady in her car and her clothes are all ripped off,” she posted on Facebook.

The alleged carjacker took off his clothes as he ran down the road, while the ute driver called his brother and a friend for help.

“Then the crazy dude strips naked and runs down the road ... he got chased by the brother and mates and jumped on their bonets and then the roof and tray,” She added.

“They caught him, king hit him and then tied the naked guys arms and legs behind his head and left him in the dirt for the police and ambulance.”

The man was taken to Armadale Hospital. He was charged with endangering a life, health or safety of a person and will face court at the end of the month.
