Father claims he was hit after alleged $30,000 motorbike theft

A Sydney father claims that after his family were robbed of $30,000 worth of motorbikes while they slept, he was then allegedly hit by one of those bikes just days later.

"I couldn't believe it … my heart absolutely dropped," Ben Clapp told A Current Affair.

Clapp said the ordeal started for him and his two sons Zane, 12, and Jai, 14, when he decided he wanted to upgrade one of their motorbikes for Christmas.

He advertised a Honda CRF150R for sale on Facebook Marketplace for $4950.

"I was contacted by a number of people (who) were interested in the bike and … I was asked to start the bike up, take some photos, send it through - I answered some questions," Clapp said.

A prospective buyer asked to inspect the bike, so Clapp agreed, gave him his address and they organised a time.

"I thought from my messages back that he was a genuine buyer, that he would turn up sometime after 5.30 to have a look at the bike, make a cash purchase, buy the bike and take the bike away," Clapp said.

But the man never showed up and that night Clapp was robbed instead - but he doesn't know by who.

"Three intruders came into the property and stole over $30,000 worth of bikes, four motorbikes and one high-end pushbike," the father claimed.

Security vision showed three alleged masked intruders casing Clapp's home for two hours before they broke into the garage.

The dad and his two young boys were asleep in their beds when they claimed it all happened.

"(It's) very scary … to think that somebody has come in, taken their Christmas presents with total disregard for them sleeping in their beds," Clapp said.

"The safety of their home has been lost."

The father said he kept the four motorbikes locked together in the garage with an alloy lock, in the event of a break-in, but the alleged thieves came prepared.

"Once they were in the garage they must have used bolt cutters to go through," he said.

Then Clapp claimed that one by one, the bikes were pushed up the street.

The alleged robbers then came back for fuel and oil, before taking off for good.

Clapp reported the robbery to police and managed to recover a helmet and jerrycan from bushland nearby.

But he said the following Friday, after the robbery took place that things got even worse.

"I was out walking and I heard one of the bikes coming down the street," he said.

"As that bike approached, I made an attempt to stop that person on the bike and he was travelling at about 50 or 60 kilometres on the road towards me.

"As I jumped out in front of him signalling to stop, he powered the bike up and ran me over."

Clapp wasn't injured but said he is worried someone else will be.

"I've been told by a number of people who have contacted me through Facebook that they have seen the bikes and I worry that an innocent person is going to be seriously injured or killed," Clapp said.

The father said he has been told that even though some of the young alleged thieves have been spotted riding the bikes on local streets, police haven't been able to chase them because they weren't wearing helmets.

Clapp said the bikes weren't insured either, due to high premiums.

He now has some advice for others thinking of advertising on Facebook Marketplace.

"Don't advertise on Facebook. You don't know who you're dealing with, who is behind that name, who is behind that profile," Clapp said.

"They absolutely fooled me."
