An 18-year-old service station attendant has described the chaos that unfolded during the first of three armed robberies in the Mandurah area on Monday night.

Hannah was working by herself at the Puma service station on Pinjarra Road in Barragup when two men entered the store about 7.10pm.

The men had their faces covered with beanies, sunglasses and bandannas and one of them was laughing, so the teenager initially thought they were joking around.

“I was just cleaning out trays in the kitchen and I’d come back to the counter to grab the other lot of trays,” Hannah said.

“I saw the guys walking in and I saw the bandannas and at first I thought it was a joke.

“They were screaming and yelling about it being a robbery, and one of the guys was skipping around and laughing, so I just laughed as well.

“Then I saw that the guy that was skipping around was waving an axe and the other guy had a yellow metal baseball bat.”

The axe-wielding robber then walked towards Hannah, smashed a glass display shelf with the axe and demanded she open the cash register.

As she stood rooted to the spot, the man with the baseball bat rounded the counter and threatened to hurt her if she didn’t comply.

“He said, ‘Open your till or I’ll bash you,’ so I did,” she said.

“I was in shock that they’d actually smashed the counter.

“I tried to move out of his way and he was like, ‘Don’t you f*cking move.'”

While the man carrying the baseball bat stole cash from the register, his accomplice stole dozens of packets of cigarettes.

One of them told Hannah he was robbing the service station because he was $10,000 in debt.

“He said, ‘If I don’t do it, I’m screwed,” Hannah said.

The men even told her it was nothing personal and said, ‘thank you,’ on the way out.

“Once they left I went and finished the trays and swept the floor because I hadn’t taken it what happened,” she said.

“It took about five minutes for it to hit me. I was a total mess.

“I was in the kitchen because I was too scared to go back out there.

“I waited until I’d given them enough time to leave, then I called my partner and the police.”

Police believe the same men held up two other businesses later that night – Falcon Bay Fish and Chips on Baroy Street just before 8pm and the Caltex service station on Mandurah Road in Meadow Springs about 9.30pm.

They were described as fair-skinned and in their mid-to-late-20s with Australian accents.

One of them had a chunky gold ring and a black and white tattoo on his left hand, possibly in the form of a rose.

He had a large build.

The other man had a slim build.
