A Melbourne father says he had a knife held to his throat when a gang of armed thugs smashed down his front door in a terrifying home invasion this morning.

Up to six youths stole a haul worth more than $70,000 after they stormed inside the family's home on Ramptons Rd, Eltham about 5.30am.

Ramiz Makouei, 34 told 9News he begged for the safety of his wife and two-year-old son, when the family awoke to the offenders.

"They were shouting and they started punching and kicking us … a few of them had a knife," he said.

"They were asking for money and car keys. We just gave it to them, everything that we had."

The offenders terrorised the family with knives and a taser, while they trashed the property. A laptop, two iPhones and a wallet with cash are among the items that were stolen in the invasion.

Mr Makouei claimed he suffered minor injuries to his face, after the youths allegedly punched his eyes and lips.

The thugs then demanded the keys to his Range Rover, before they fled the scene in a getaway car and the family's 2018 Holden Commodore.

"You can't do anything, it's really frustrating," Mr Makouei said.

"[We were] stressed, panicking and scared.

"From now on it's going to really affect our family."
