The Block's Adrian 'Mr Lambo' Portelli hits back at claims break-in at his $40m penthouse was a publicity stunt

Adrian Portelli has denied a recent break-in at his Melbourne penthouse was a 'publicity stunt'. 

The billionaire, known as 'Mr Lambo', saw security video of two men entering his $40million property and inspecting his $3 million McLaren sports car. 

However, the thieves left empty handed, as the penthouse was 57 floors up and the would be burglars had no way to remove the car.    

'It's definitely not a set-up. I've got better things to do,' Portelli told A Current Affair on Monday, adding that he feels 'unsafe' after the incident. 

'The fact that there's people wandering around the building who shouldn't be there is concerning for everyone,' he said. 

A police spokesperson confirmed that the Victorian force was investigating a 'trespass incident' at the property. 

'It is understood two male offenders gained access to a residence between 11pm on Sunday 25 and 2am on Monday 26 August,' the spokesperson said. 

Adrian did see the funny side of thieves breaking in to steal a car from a top floor apartment. 

'Boys, if you want to try and steal a car don't try and steal one that's 57 floors up,' he said. 

It's not the first break-in Portelli has endured this year. 

In February, Adrian offered a whopping reward to anyone who can identify a group of wannabe thieves who broke into his office and left empty-handed.

Portelli shared two CCTV videos of the group inside his north Melbourne office after the clueless thieves gained entry through a smashed window.

The 35-year-old - who's best known online for giving away thousands of dollars through his savings subscription, LMCT+, and bidding on properties from The Block - said he wanted to ensure the thieves are caught because he's 'just has a kid'.

'I don't need f**kheads like this breaking into my s**t ... It's f**king disrespectful,' he told his Instagram followers.

Portelli initially offered $100,000 for the identity of the thieves but doubled the reward to $200,000 on Thursday afternoon.

'I'm upping it up to $200,000 for whoever can get me the names of the people who broke into this shop last night,' he told his 292,000 Instagram followers.

'If you've got the information, come forward. You will remain anonymous. Let's end this, once and for all.' 

CCTV shows at least four people, one armed with a sledgehammer, scouring the office for anything of value.

The group fled in a dark-coloured four-door ute, which was also captured on CCTV.

Portelli revealed why they 'left empty-handed in their pursuit of happiness'.

'They thought they were going to be welcome to a big pot of gold so they could run away to Barbados and live off the money,' he said.

'Guys, I do not keep money, keys, anything of value on site. There's nothing here.

'If you want yourself a Coco Republic couch you're more than welcome to break in and come steal it, but if you want cash or any other goodies there's nothing here.

'I'm from the west as well, mate. You think I'm gonna publicise all this cash and then be like, 'it's at the factory guys, help yourself to it'?

'Smarten up.'

While nothing was stolen, footage from the break-in aftermath showed damaged computers and overturned furniture.

Portelli joked that the group actually did him a favour.

'You've given me a bunch of new content that I actually desperately needed,' he said

'We were running low on content. You guys did me wonders. But if you do want to win $350,000 the legal way, here is the link here. 

'It's only $10, it's a lot less effort than stealing a car, breaking into a place, now you've got all the police on your tail and your mates will probably rat you out for $200,000.' 

Portelli decided to 'make some fun of it' and opened the investigation to his followers, alongside the cash prize. 

'We're going to play a game, it's called convict the criminal,' he said.

He promised to give anyone who can give 'information leading to a conviction' an 'instant transfer' of $200,000.
