Frankston Crime Investigation Unit detectives are appealing for public assistance following a series of aggravated burglaries in Langwarrin.
Investigators understand the unknown male offender entered a house on Wattlebird Crescent an attempted to steal car keys before he was confronted by a resident and ran to a neighbouring property about 6.35pm on Sunday, 14 July.
The offender was again confronted by a resident and jumped a fence before entering the garage of a third residence.
It is believed the offender accessed two vehicles but was unable to get them started and fled.
The same offender has then attended a fourth house and again been challenged by a resident who ushered the offender off the property.
Unbeknownst to the victim, the offender had managed to take car keys from inside the residence and once outside he stole a 2021 Mazda CX5 wagon with registration 1Zn 5SU.
The offender was perceived to be Caucasian in appearance, about 168cm tall with a skinny build, and spikey blond hair.
He was wearing a lime green-coloured top and had a distinctive, large dog collar around his neck.
The residents who confronted the victim reported him appearing to have pre-existing facial injuries.
Investigators have also been told the offender made claims to residents that people had assaulted him.
Detectives have concerns about the bizarre circumstances surrounding the incidents and are hoping to identify the offender and speak with him, not only regarding the Langwarrin incidents but also to establish whether he needs medical treatment or was subject to any earlier offending.
Anyone who sees the stolen Mazda, or has information that can assist police with their enquiries is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
