Kingston Crime Investigation Unit detectives are investigating following a ram raid in Patterson Lakes this morning.

A silver Holden Colorado utility has reversed through the front windows of a supermarket, at the intersection of Gladesville Boulevard and McLeod Road, about 4am.

The two male occupants have entered the store and attempted to break into a cigarette cabinet.

They have been disturbed by a number of bakers in the store and have fled.

A staff member, who had just pulled up in his car to start work for the day, has followed the offenders along Eastlink.

The two vehicles were involved in a collision a short time later near Thompson Road in Carrum Downs.

The burglars drove off and the cause of the crash is being investigated.

The staff member was not injured.

The first man is perceived to be of Caucasian appearance, with a solid build, wearing a dark windcheater, white pants and was wearing a balaclava.

The second man is perceived to be of Caucasian appearance, with a slim build, wearing a dark top, dark three-quarter length pants and a dark baseball cap.

Detectives believe the silver utility, which has a black tray covering, will have damage to its back end and tail lights.
