Police have arrested two teenagers following two armed robberies in Caroline Springs and Sydenham last night (23 August).

The first incident occurred at a restaurant on Lake Street in Caroline Springs about 9.50pm.

Three males, perceived to be Caucasian in appearance, allegedly entered the premises armed with metal bars and a meat cleaver.

A number of items were smashed and they allegedly attempted to steal the cash register but left empty-handed in a vehicle.

The second incident took place at a bottle shop on Hume Drive in Sydenham about 10pm.

Three males with bandanas covering their faces entered the store, allegedly armed with a meat cleaver.

A staff member picked up a baseball bat and the offenders fled empty-handed in a vehicle. No one was physically injured during the incidents.

A 16-year-old Sydenham boy and an 18-year-old Melton South man were arrested at a Taylors Hill address this morning.

Both are currently in custody, assisting police with their enquiries.

Police have also recovered a vehicle, a Honda sedan, believed to be used during the two incidents.

The investigation remains ongoing and police are still searching for the remaining offenders.
