Police investigating two aggravated robberies overnight have arrested two alleged offenders for one of the hold-ups.

The first robbery was at about 12.12am when a man armed with a knife threatened staff at the Mobil Quix service station on Bridge Road, Para Hills.

He stole cash before fleeing on foot towards Williamson Road and was last seen heading towards McIntyre Road.

He is described as being about 40 years, grey hair and wearing a grey hooded top, grey tracksuit pants and a dark coloured cloth or similar over his face.

The second robbery was at about 2.14 am at the BP On the Run servo on Peachy Road, Davoren Park.

Two men, one armed with a pair of scissors and the other a knife threatened the staff member who suggested to the offenders, “it’s not worth it.”

One offender threatened to jump the counter before both decided to leave empty handed.

Patrols quickly on scene stopped two men nearby and spoke to them.

One was allegedly in possession of a knife and after checking CCTV vision for descriptions of the offenders, the two were arrested.

A 20-year-old man from Davoren Park and a 19-year-old of no address have been charged with attempt aggravated robbery.

Bail has been refused and it is expected they will appear in Court later today.
