Jordan Sudmeyer, 37, woke up about 4.30am to get ready for work at 5am.

“I noticed about 4.30 someone had been in the house,” he said.

“Tablets and wallets were missing.”

The aggravated burglary was one of three in Warrnambool overnight.

Mr Sudmeyer’s wife Maxine and their two children Mason, 5, and Heidi, 3, slept through the home invasive.

The family’s two vehicles were also stolen from their Giffen Street home.

“We’re a bit shaken up,” Mr Sudmeyer said.

“It’s a kick in the guts to have both cars stolen.”

Mr Sudmeyer’s Holden Captiva was found dumped on the corner of Goodall and McMahon streets on Wednesday morning.

The vehicle had been damaged in a collision and was undriveable.

Homes in Merri Street and Lindsay Street in Dennington were also targeted.

Detective Senior Constable Richard Hughes of the Warrnambool police crime investigation unit, said the home invasions occurred between 11pm and 5am while the occupants of the homes were sleeping.

A year 12 student’s MacBook Pro was stolen from the Merri Street property, while another vehicle was stolen from a home in Lindsay Street.

Detective Senior Constable Hughes said the three incidents were “quite possibly” connected.

“It’s a timely reminder for occupants of Warrnambool to have their houses locked. Lock your back and front door and make sure your cars are locked – the days of leaving doors unlocked in Warrnambool are over,” Detective Senior Constable Hughes said.

He said there had been a number of similar incidents in recent months, with an aggravated burglary in Eddington Street in late April.

“In all of these incidents it appears they have got in through unlocked doors,” Detective Senior Constable Hughes said.

He urged anyone who witnessed any suspicious behaviour overnight or anyone with information about the incidents to contact Warrnambool police or Crime Stoppers on 1800 333 000.
