Police were attempting to identify two men who were seen acting suspiciously in Armadale last month.
About 7.50am on May 18 two men were seen with a white four-door sedan parked on Seventh Road west of the CBD.
The vehicle had no registration plates on the front or rear and was parked near a pay phone.
One of the men crossed the road and entered the nearby IGA while the second man drove the car.
The first man entered the IGA and made a purchase as the car made a u-turn and picked him up before driving away.
The first man was described as dark skinned with a large build and about 170-centimetres.
He was wearing a grey hooded top, shorts and with a large black bag over his right shoulder.
The second man was described as dark skinned, about 175-centimetres with a thin build and short dark hair.
Anyone with information was asked to call Crime Stoppers on 1800 333 000 or make a report online at crimestopperswa.com.au.
