An armed robbery involving $25,000 of gold and silver bullion in Melbourne's outer-east has prompted a police appeal for further information.
The robbery occurred on March 27 at a home in Marykirk Drive, Wheelers Hill.
A man pulled up at the home about 9.40pm when he was confronted by two masked men, one armed with a firearm.
The victim, a Wantirna man, was robbed and had his hands tied with cable ties.
The two offenders then fled in a light-coloured four-wheel drive with gold and silver coins and bars. The vehicle had off-road extras including a black bull bar, a snorkel and off-road tyres.
It was last seen heading south on Marykirk Drive.
The two offenders are about 175cm tall and were wearing dark clothing and balaclavas. One of the men had bushy eyebrows and is of European appearance.
Armed Crime Task Force detectives are investigating the case.
Anyone with information is asked to phone Crime Stoppers on 1800 333 000.
