[The Australian]- A MAN has smashed his way into an adult shop and had sex with blow-up dolls before abandoning the sex toys in a nearby lane.

Business owners in Cairns believe the same culprit is responsible for break-ins and till thefts at the Sapphire Bar on Lake St and three break-ins at the Laneway Adult Shop off Spence St in recent days.

His method of entry is to smash through walls and squeeze through tight holes, The Cairns Post reports.

The owner of the adult shop, who wished to be named only as Vogue, said that in a first unreported break-in, the man had stolen five dolls and had sex with one of them.

“He has been taking the dolls out the back and blowing them up and using the dolls and leaving them in the alley,” he said.

“It is totally bizarre. It is a real concern that someone like that is out on the street.”

Vogue said a sex toy also went missing in the second break-in and that the offender had a liking for the doll model named “Jungle Jane”, which had been taken on both occasions.

He said he was dumbfounded that the burglar also had the “weird” habit of cleaning up the mess he had made after entering the building.

The burglar again smashed through a wall in the roof area of the shop on either Monday night or early yesterday morning but was scared off by a newly installed alarm system.

Vogue and David Sharman, the owner of the Sapphire Bar on Lake St that has a rear entry in the same lane as the adult shop, both believe they have been targeted by the same thief.

Both men said fleeting video images showed the burglar as being a tall, skinny Caucasian. He has left DNA evidence at the crime scene.

Mr Sharman said in one break-in at his business: “The burglar smashed a hole near the top of the roof line. He then clambered 15m down a sheer wall.

“He (only) took the surveillance recorders – we found them in the bin.”
